Description
Technical Field
[0001] This utility model relates to the field of irregular part clamping technology, and in particular to a clamping device for processing irregular parts on a CNC lathe. Background Technology
[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, cylindrical and conical threads, etc. of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations. For the processing of automotive parts, CNC lathes are generally used.
[0003] A search revealed a CNC lathe clamping device for machining automotive parts, disclosed in publication number CN218426985U. This device includes a fixed base, a base fixedly mounted on the side of the fixed base, a sliding seat at the top of the base, a support base fixedly mounted on the side of the base, a groove on the right side of the fixed base, a drive motor fixedly mounted inside the fixed base, a rotating shaft driven onto the output shaft of the drive motor, a disc fixedly mounted on the right side of the rotating shaft, a support rod inside the disc, a spring fixedly mounted between the disc and the support rod, a rubber head fixedly mounted at the top of the support rod, a sliding groove at the top of the base, a slider between the sliding seat and the sliding groove, a cylinder fixedly mounted inside the support base, a push plate fixedly mounted on the movable end of the cylinder, and a left side of the push plate fixedly connected to the right side of the sliding seat.
[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, due to the fixed specifications of the groove and the large number of springs, support rods and rubber heads, the specifications of the spring will be reduced, which will affect the strength of the spring and thus make it impossible to stably clamp the irregular parts. Therefore, we propose a clamping device for machining irregular parts on CNC lathes. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a clamping device for machining irregularly shaped parts on a CNC lathe, which can solve the problems existing in the background art.
[0006] The technical solution of this utility model is:
[0007] A clamping device for machining irregularly shaped parts on a CNC lathe includes a mounting base. One end of the mounting base has symmetrically arranged electric telescopic rods. The output end of the electric telescopic rods is fixedly connected to a movable mounting block. Both the movable mounting block and the other end of the mounting base have servo motors inside. One side of the movable mounting block and the inner side of the other end of the mounting base are connected to a connecting mounting sleeve block via the servo motors. One side of the connecting mounting sleeve block has a connecting limit block. The inner side of the connecting mounting sleeve block has a connecting clamping and fitting mechanism. One side of the connecting clamping and fitting mechanism is fixedly connected to a connecting air pipe, and the other end of the connecting air pipe is connected to an air pump.
[0008] In a further technical solution, the mounting base is provided with symmetrical fixed mounting grooves on its inner side, and a movable mounting plate is movably connected to the inner side of the fixed mounting groove. The mounting base and the movable mounting block are connected and fixed to the movable mounting plate by bolts, and an auxiliary reset mechanism is fixedly connected to one side of the movable mounting plate.
[0009] In a further technical solution, the connecting clamping and fitting mechanism includes a connecting mounting box, a plurality of fixing sleeves are provided on one side of the connecting mounting box, a connecting piston is movably connected to the inner side of the fixing sleeves, and a connecting limiting rod is fixedly connected to one side of the connecting piston.
[0010] In a further technical solution, the surface of the connecting mounting sleeve is provided with a through groove that matches the connecting limiting top rod.
[0011] In a further technical solution, the support plate of the connecting limiting block is in contact with the inner side of the connecting mounting sleeve and the outer side of the fixing sleeve, and the upper and lower ends of the connecting limiting block are respectively in contact with one end of the upper and lower ends of the connecting mounting sleeve.
[0012] In a further technical solution, the auxiliary reset mechanism includes a connecting guide frame, the inside of which is provided with a fixing groove, a drive motor is fixedly connected to the top of the connecting guide frame, and a drive rubber wheel is fixedly connected to the output end of the drive motor.
[0013] In a further technical solution, the outer surface of the connecting air tube is in contact with the inner side of the fixing groove and the outer side of the driving rubber wheel.
[0014] The beneficial effects of this utility model are:
[0015] 1. Through the cooperation of the connecting mounting sleeve, connecting limiting block, connecting clamping and fitting mechanism and connecting air pipe, when clamping and fixing irregular parts, the end of the connecting clamping and fitting mechanism can contact the outer surface of the irregular part and move telescopically. When the end of the connecting clamping and fitting mechanism is in stable contact with the outer surface of the irregular part, the air pump can deliver compressed gas to the inside of the connecting clamping and fitting mechanism through the connecting air pipe, thereby acting on the connecting clamping and fitting mechanism so that the connecting clamping and fitting mechanism can stably clamp and fix the irregular part.
[0016] 2. With the auxiliary reset mechanism, when the connecting mounting sleeve drives the connecting clamping and fitting mechanism to rotate, thereby causing the irregular part to flip over, the connecting air pipe can be moved. When the connecting mounting sleeve rotates in the opposite direction to reset, the auxiliary reset mechanism can drive the connecting air pipe to reset, improving stability, preventing the connecting air pipe from falling off and affecting the lathe's processing, and also preventing the lathe from damaging the connecting air pipe. The operation is convenient. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] Example:
[0025] like Figures 1-4 As shown, a clamping device for machining irregular parts on a CNC lathe includes a mounting base 1. One end of the mounting base 1 has symmetrically arranged electric telescopic rods 2. The output end of the electric telescopic rods 2 is fixedly connected to a movable mounting block 3. Both the movable mounting block 3 and the mounting base 1 have servo motors inside. One side of the movable mounting block 3 and the inner side of the other end of the mounting base 1 are connected to a connecting mounting sleeve block 4 via the servo motors. One side of the connecting mounting sleeve block 4 has a connecting limit block 5. The inner side of the connecting mounting sleeve block 4 has a connecting clamping and fitting mechanism 6. One side of the connecting clamping and fitting mechanism 6 is fixedly connected to a connecting air pipe 7, and the other end of the connecting air pipe 7 is connected to an air pump.
[0026] The working principle of the above technical solution is as follows:
[0027] During use, the irregularly shaped part is first placed between the connecting clamping and fitting mechanism 6. Then, the electric telescopic rod 2 can move the movable mounting block 3, the connecting mounting sleeve block 4, the connecting limiting block 5, the connecting clamping and fitting mechanism 6, and the connecting air pipe 7, so that the connecting clamping and fitting mechanism 6 can fit with the irregularly shaped part and perform initial clamping on the irregularly shaped part. Then, the air pump delivers compressed air to the inside of the connecting clamping and fitting mechanism 6 through the connecting air pipe 7, so that the connecting clamping and fitting mechanism 6 can perform clamping processing on the irregularly shaped part, thereby enabling stable processing of the irregularly shaped part. The operation is convenient.
[0028] In another embodiment, such as Figure 1 As shown, the mounting base 1 has symmetrical fixed mounting grooves 8 on its inner side. The fixed mounting grooves 8 are movably connected to the inner side of the fixed mounting grooves 8. The mounting base 1 and the movable mounting block 3 are connected and fixed to the movable mounting plate 9 by bolts. An auxiliary reset mechanism 10 is fixedly connected to one side of the movable mounting plate 9.
[0029] The servo motor facilitates the rotation of the connecting mounting sleeve 4, connecting limit block 5, connecting clamping and fitting mechanism 6, and irregular parts. When the irregular parts are flipped, the connecting air pipe 7 will be pulled. When the connecting mounting sleeve 4, connecting limit block 5, connecting clamping and fitting mechanism 6, and irregular parts are rotated in the opposite direction to reset, the connecting air pipe 7 can be driven to reset under the action of the auxiliary reset mechanism 10, so as to avoid the connecting air pipe 7 from bending and affecting the lathe processing. The operation is convenient.
[0030] In another embodiment, such as Figure 2As shown, the connecting clamping and fitting mechanism 6 includes a connecting mounting box 11. A plurality of fixing sleeves 12 are provided on one side of the connecting mounting box 11. A connecting piston 13 is movably connected to the inner side of the fixing sleeves 12. A connecting limiting rod 14 is fixedly connected to one side of the connecting piston 13.
[0031] The air pipe 7 facilitates the delivery of compressed air into the interior of the mounting box 11, allowing the compressed air to be delivered to the inside of the fixed sleeve 12 and push the connecting piston 13, which in turn moves the connecting limit rod 14. This enables the end of the connecting limit rod 14 to stably clamp the irregularly shaped parts, making operation convenient.
[0032] In another embodiment, such as Figure 2 As shown, the surface of the connecting mounting sleeve 4 is provided with a through groove that matches the connecting limiting rod 14.
[0033] When the connecting mounting housing 11, the fixing sleeve 12 and the connecting limiting rod 14 move laterally towards the inside of the connecting mounting sleeve 4, the connecting limiting rod 14 can move inside the through groove on the surface of the connecting mounting sleeve 4, making operation convenient.
[0034] In another embodiment, such as Figure 2 As shown, the support plate of the connecting limit block 5 is in contact with the inner side of the connecting mounting sleeve 4 and the outer side of the fixing sleeve 12, and the upper and lower ends of the connecting limit block 5 are respectively in contact with one end of the upper and lower ends of the connecting mounting sleeve 4.
[0035] The connection limit block 5 can be stably attached to the outer side of one side of the connecting mounting sleeve block 4 and fixed by bolts, which can make the connection stable. At the same time, it can also limit and position the connecting mounting box 11 and the fixing sleeve block 12, which can be used stably and is easy to operate.
[0036] In another embodiment, such as Figure 3 As shown, the auxiliary reset mechanism 10 includes a connecting guide frame 15, a fixing groove 16 is provided inside the connecting guide frame 15, a drive motor 17 is fixedly connected to the top of the connecting guide frame 15, and a drive rubber wheel 18 is fixedly connected to the output end of the drive motor 17.
[0037] This allows the drive motor 17 to drive the drive rubber wheel 18, enabling the connecting air pipe 7 to move between the fixed groove 16 and the inner side of the drive rubber wheel 18 when the drive rubber wheel 18 rotates. This facilitates the resetting of the connecting air pipe 7 and makes operation convenient.
[0038] In another embodiment, such as Figure 3 and Figure 4As shown, the outer surface of the connecting tube 7 is in contact with the inner side of the fixing groove 16 and the outer side of the driving rubber wheel 18.
[0039] The air tube 7 is easily connected and can be stably positioned inside the fixed groove 16 and the edge of the drive rubber wheel 18, making operation convenient.
[0040] The working principle of this utility model is as follows: During use, the irregularly shaped part is first placed between the ends of the connecting limiting rod 14. Then, the electric telescopic rod 2 moves the mounting block 3 to push it, allowing the end of the connecting limiting rod 14 to contact the irregularly shaped part and retract automatically, fully fitting against the outer surface of the irregularly shaped part for initial clamping. Next, the air pump delivers compressed air through the connecting air pipe 7 to the inside of the connecting mounting box 11 and the fixing sleeve 12. Under the action of the compressed air, the connecting piston 13 and the connecting limiting rod 14 are pushed, thereby stably clamping the irregularly shaped part. During processing... During the process, the servo motor can flip the connecting mounting sleeve 4, connecting limit block 5, connecting clamping and fitting mechanism 6, and the irregular part as a whole. At this time, the connecting air pipe 7 can be pulled. When the processing is completed and the reverse reset is performed, in order to prevent the connecting air pipe 7 from being unable to move and reset on its own, which would cause bending and affect the lathe processing, and also to prevent the lathe from damaging the connecting air pipe 7, the drive motor 17 resets the drive rubber wheel 18. When the drive rubber wheel 18 rotates, the connecting air pipe 7 can move inside the fixed groove 16, thereby resetting the connecting air pipe 7. The overall structure is simple and the operation is convenient and quick.
[0041] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
