Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and more specifically, to a feeding mechanism for machined parts. Background Technology

[0002] Parts are basic components that can be assembled into machines, instruments, and various equipment. When machine tools perform precision machining on them, clamping mechanisms are needed to grip and move them, reducing manual operation.

[0003] However, existing loading mechanisms typically use independent robotic arms to clamp parts for transport and loading. But when clamping and loading thin sheet parts, mechanical clamping can easily lead to concentrated clamping force, causing indentations or even deformation, affecting the quality of the parts. Some loading mechanisms use suction cups for negative pressure adsorption and handling of parts. Suction cups do not damage the surface of the shell parts, effectively reducing the risk of deformation of thin-walled shell parts during handling. However, when using suction cups, unstable air pressure or jig vibration can easily break the firm adhesion of the suction cups to the shell parts, easily causing vacuum loss, resulting in the shell parts falling off the suction cups and falling damage. Furthermore, suction cup adsorption is not effective for handling rough, blocky parts, making it impractical. Utility Model Content

The front and rear sides of the bearing base are fixedly connected to first guide rails. Adjustment parts, two of which are symmetrically slidably mounted at both ends of the bearing seat; The clamping parts are respectively fixed to the bottom of the two adjusting parts, wherein... Drive the lifting unit, and the two clamping units move vertically to clamp the parts at the feeding position and the processing position. Drive the translation unit, and the lifting unit moves horizontally, so that the parts at the feeding position and the processing position move to the processing position and the discharge position, respectively.

[0006] Furthermore, the clamping part includes a pneumatic gripper fixed to the bottom of the adjusting part, two translation frames fixed to the two telescopic ends of the pneumatic gripper, two clamping seats respectively disposed at the bottom of the two translation frames, two clamping blocks respectively fixed to the lower ends of the two clamping seats, two V-shaped slots respectively opened on the two clamping blocks, and two connecting members respectively disposed on the two translation frames and connected to the two clamping seats. Both clamping blocks are fixedly fitted with rubber sleeves, and both rubber sleeves are provided with friction ridges on their outer surfaces.

[0007] Furthermore, the clamping part also includes a mounting plate fixed to the lower surface of the pneumatic gripper, a plurality of suction cup tubes fixed in a ring array to the lower surface of the mounting plate, a plurality of suction pipes connected at one end to the plurality of suction cup tubes and at the other end to an external air pump structure, and miniature solenoid valves respectively installed on the plurality of suction pipes.

[0008] Furthermore, the connecting member includes two supports symmetrically fixed on the clamping seat, two limiting rods respectively fixed on the two supports, two guide grooves symmetrically opened on the translation frame and allowing the upper ends of the two limiting rods to move, two return springs respectively movably sleeved on the two limiting rods and fixed at both ends to the upper surface of the support and the lower surface of the translation frame, a limiting block fixed on the clamping seat, a limiting groove opened on the translation frame and allowing the limiting block to move, and a limiting bolt threaded to the bottom of the translation frame and abutting against the limiting block; The upper ends of both limiting rods are fixed to the upper end of the clamping seat.

[0009] Furthermore, the adjusting part includes two first guide blocks that are slidably mounted on two first guide rails respectively, an adjusting sleeve fixed on the two first guide blocks, two positioning bolts that are symmetrically threaded on the front and rear sides of the adjusting sleeve, and a scale groove opened on the bearing seat. The heads of the two positioning bolts abut against the front and rear sides of the bearing seat, respectively; The pneumatic gripper is fixed to the lower surface of the adjustment sleeve.

[0010] Furthermore, the translation part includes two second guide rails symmetrically fixed to the front surface of the base, several second guide blocks slidably mounted on the two second guide rails and fixedly connected to the translation plate, a screw adjustment mechanism disposed at one end of the base, two control gears rotatably mounted on the base and the screw adjustment mechanism, a control toothed belt meshing on the two control gears and fixed to the translation plate, and a drive motor mounted on the base; The output end of the drive motor is fixedly connected to one of the control gears.

[0011] Furthermore, the lifting unit includes an electric push rod fixed on the mounting base, a lifting seat fixed to the telescopic end of the electric push rod and placed below the mounting base, symmetrically fixed to the upper surface of the lifting seat, and both guide rods passing through the mounting base; The support seat is fixed to the lower surface of the lifting seat.

[0012] Compared with the prior art, the embodiments of this utility model have the following beneficial effects: This machining parts loading mechanism, through the combination of a translation unit and a lifting unit, can control the vertical and horizontal position of the parts held by the clamping unit for stable adjustment. Furthermore, the clamping unit is mounted on the support seat via an adjustment unit, which facilitates the adjustment of the distance between the two clamping units. This allows the two clamping units to simultaneously and accurately clamp parts at both the loading and processing positions. While loading parts, the parts at the processing position can be simultaneously transferred to the unloading position, achieving synchronous loading and unloading of parts and ensuring efficient parts loading and processing. This machining parts loading mechanism, through the cooperation of two connecting parts in the clamping section, allows two clamping seats in the clamping section to be movably connected to two translation frames. Thus, when loading rough, blocky parts, the pneumatic grippers cause the two translation frames to move the two clamping seats closer together, allowing the two clamping blocks to directly contact the part for clamping. When loading smooth, thin sheet parts, as the lifting unit controls the continuous downward movement of the clamping section, the two clamping seats can move upward relative to the two translation frames, thereby causing several suction cup components at the bottom of the pneumatic grippers to... The negative pressure adsorption of the parts avoids deformation and damage to thin sheet parts caused by mechanical clamping. After the adsorption stabilizes, the lifting unit controls the clamping part to move upward. At this time, under the elastic force of the return spring in the connecting part, the clamping seat drives the clamping block to return to its original position. Then, under the operation of the pneumatic gripper, the two clamping blocks move closer to each other, which can support the bottom of the thin sheet part, thereby effectively preventing the parts from falling accidentally due to vacuum adsorption failure. This ensures the reliability of high-speed material handling and feeding of parts under vibration environment. Furthermore, when feeding parts of different shapes, there is no need to make too many adjustments to the feeding mechanism, which effectively improves practicality. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-6 As shown, a machining parts feeding mechanism includes: a support 1, a base 2 fixedly connected to the upper end of the support 1, a translation plate 3 provided on the front surface of the base 2, and an assembly seat 4 fixedly connected to the front surface of the translation plate 3; Translation part 5, which is mounted on the base 2 and connected to the translation plate 3; Lifting part 6 is mounted on the mounting base 4. The output end of the lifting part 6 is fixedly connected to the bearing base 7. The front and rear sides of the bearing base 7 are fixedly connected to the first guide rail 8. Adjustment part 9, two of the adjustment parts 9 are symmetrically slidably installed at both ends of the bearing seat 7; Clamping parts 10, the two clamping parts 10 are respectively fixed to the bottom of the two adjusting parts 9, wherein Drive the lifting part 6, and the two clamping parts 10 move vertically to clamp the parts at the feeding position and the processing position. Drive the translation part 5, and the lifting part 6 moves horizontally to move the parts at the feeding position and the processing position to the processing position and the discharge position, respectively. In use, the parts to be processed are transported by the external conveying mechanism to the loading area near the processing position. At this time, under the linkage of the translation unit 5 and the lifting unit 6, the carrier 7 is controlled to move horizontally and vertically, so that the two clamping units 10 on the carrier 7 can switch positions through horizontal movement. The two clamping units 10 move from the loading area to the processing area and from the processing area to the unloading area respectively, and pick up and put down the materials through vertical lifting. Through one horizontal movement, the workpieces of the feeding position and the processing position are interchanged, and the loading and unloading operations are completed simultaneously, realizing the flow of materials in two positions and ensuring the efficiency of part processing. When the clamping unit 10 clamps the material, if the part to be processed is a conventional part, the pneumatic gripper 11 can directly control the two translation frames 12 to move closer to each other, so that the two clamping seats 13 cooperate with the two clamping blocks 41 to complete the gripping of the part. The return spring 23 at the connection between the clamping seat 13 and the translation frame 12 can play a certain role in buffering. The lifting mechanism prevents the clamping part 10 from making hard contact with the part mounting surface and causing overload impact when it is lowered by the lifting part 6. If the part to be processed is a thin, smooth sheet, when the lifting part 6 controls the clamping part 10 to move down to clamp the part, the two translation frames 12 continue to move down after pushing the two clamping seats 13 away from the part mounting surface until several suction cup tubes 18 come into contact with and adsorb the part. During this process, the return spring 23 between the translation frame 12 and the clamping seat 13 is compressed. When the lifting part 6 controls the clamping part 10 to move up, the clamping seat 13 and the clamping block 41 on it are reset under the elastic force of the return spring 23. At this time, the two clamping blocks 41 move closer to each other under the drive of the pneumatic gripper 11, which can support the bottom of the thin sheet part, thereby effectively preventing the part from falling accidentally due to vacuum adsorption failure. This ensures the reliability of high-speed material handling and feeding of parts under vibration environment. Furthermore, when feeding parts of different shapes, there is no need to make too many adjustments to the feeding mechanism, which effectively improves practicality.

[0018] Optionally, the clamping part 10 includes a pneumatic gripper 11 fixed to the bottom of the adjusting part 9, two translation frames 12 fixed to the two telescopic ends of the pneumatic gripper 11, two clamping seats 13 respectively disposed at the bottom of the two translation frames 12, two clamping blocks 41 respectively fixed to the lower ends of the two clamping seats 13, two V-shaped slots 14 respectively opened on the two clamping blocks 41, and two connecting pieces 15 respectively disposed on the two translation frames 12 and respectively connected to the two clamping seats 13; Both clamping blocks 41 are fixedly fitted with rubber sleeves 16, and both rubber sleeves 16 are provided with friction ridges on their exterior. In use, under the control of the lifting unit 6, the clamping unit 10 can move down to the part position. At this time, the pneumatic gripper 11 works, controlling the two translation frames 12 to drive the two clamping seats 13 to move closer to each other, thereby making the two clamping blocks 41 approach and contact the part to perform the clamping operation. Through the V-shaped slots 14 opened on the two clamping blocks 41, it can be adapted to cylindrical parts and perform self-centering clamping to ensure the clamping stability of parts of different shapes. In addition, the rubber sleeves 16 set on the outside of the two clamping blocks 41, together with the friction ridges on the rubber sleeves 16, can effectively increase the friction of the contact surface, prevent the parts from sliding or the surface from being damaged, and ensure the stability of the parts loading.

[0019] Optionally, the clamping part 10 further includes a mounting plate 17 fixed to the lower surface of the pneumatic gripper 11, a plurality of suction cup tubes 18 fixed in a ring array to the lower surface of the mounting plate 17, a plurality of suction pipes 19 connected at one end to the plurality of suction cup tubes 18 and at the other end to an external air pump structure, and miniature solenoid valves 20 respectively installed on the plurality of suction pipes 19. In use, the external air pump operates, and through several suction pipes 19 and solenoid valves, several suction cup components 18 can be controlled to adsorb flat parts. Negative pressure adsorption eliminates mechanical squeezing, avoiding the risk of part deformation. When loading smooth, thin sheet parts, the two clamping seats 13 can be moved upward relative to the two translation frames 12 through the connecting piece 15, thus not affecting the operation of the suction cup components 18 and ensuring the normal material handling of the suction cup components 18. Since the suction cup components 18 are respectively drawn by negative pressure through several suction pipes 19, and the miniature solenoid valves 20 on the suction pipes 19 all drive pressure sensors, changes in airflow pressure can be detected. Therefore, if a single suction cup component 18 fails to adsorb due to an accident, the pressure sensor detects this and the miniature solenoid valves seal the suction pipe 19 connected to that suction cup component 18, thus not affecting the adsorption effect of the remaining suction cup components 18 and ensuring the adsorption stability of the parts.

[0020] Optionally, the connector 15 includes two supports 21 symmetrically fixed on the clamping seat 13, two limiting rods 22 respectively fixed on the two supports 21, two guide grooves 24 symmetrically opened on the translation frame 12 and respectively allowing the upper ends of the two limiting rods 22 to move, two return springs 23 respectively movably sleeved on the two limiting rods 22 and fixed at both ends to the upper surface of the support 21 and the lower surface of the translation frame 12, a limiting block 25 fixed on the clamping seat 13, a limiting groove 26 opened on the translation frame 12 and allowing the limiting block 25 to move, and a limiting bolt 27 threadedly connected to the bottom of the translation frame 12 and abutting against the limiting block 25; The upper ends of both limiting rods 22 are fixed to the upper end of the clamping seat 13; When the clamping part 10 is lowered by the lifting part 6 and approaches the part, the clamping seat 13 and the clamping block 41 will pre-contact the placement plane of the part. At this time, if it is for clamping blocky, non-smooth connected parts, the clamping part 10 will no longer move down, and the pneumatic gripper 11 will work to control the two clamping seats 13 and the two clamping blocks 41 to move closer to each other to clamp the part. However, if it is for clamping thin, smooth parts, as the clamping part 10 continues to move down, the two limiting rods 22 on the clamping seat 13 will move in the two guide grooves 24 respectively. The return springs 23 outside the positioning rod 22 are compressed, and several suction cup tubes 18 will adsorb the upper surface of the part through negative pressure. At this time, the pneumatic gripper 11 is not closed, and only the suction cup tubes 18 work. After the suction cup tubes 18 stably adsorb, the lifting part 6 controls the clamping part 10 to move upward. Under the elastic force of the return spring 23, the clamping seat 13 and the clamping block 41 are reset. At this time, the pneumatic gripper 11 slowly closes, and the clamping block 41 can approach the part and lift the bottom of the part, forming a stable clamping state of upper suction and lower support. The two clamping seats 13 can be relatively translated. The frame 12 moves vertically, and under the elastic force of the return spring 23, it can keep the two clamping seats 13 away from the translation frame 12. Therefore, when it is necessary to use several suction cups 18 to adsorb and clamp parts, the two clamping seats 13 can be squeezed upwards without affecting the normal adsorption and clamping operation of the suction cups 18. When the return spring 23 pushes them downwards to reset, the clamping blocks 41 on the two clamping seats 13 can be controlled by the pneumatic grippers 11 to move closer together, lifting the bottom of the part, thus avoiding deformation of thin sheet parts during clamping. This effectively prevents accidental drops during the material loading process, ensuring the reliability of parts handling in vibration environments. Furthermore, when the clamping seat 13 moves vertically relative to the translation frame 12, the limiting block 25 moves synchronously in the limiting groove 26. By rotating the limiting bolt 27, the movement distance of the limiting block 25 in the limiting groove 26 can be effectively limited. This allows adjustment of the vertical distance between the clamping block and several suction cup tubes 18 in the initial state to adapt to the thickness of the parts, ensuring that the clamping block can effectively support the bottom of the parts during subsequent clamping.

[0021] Optionally, the adjusting part 9 includes two first guide blocks 28 that are slidably mounted on two first guide rails 8 respectively, adjusting sleeves 29 fixed on the two first guide blocks 28, two positioning bolts 30 that are symmetrically threaded on the front and rear sides of the adjusting sleeves 29, and a scale groove 31 opened on the bearing seat 7. The two positioning bolts 30 abut against the front and rear sides of the bearing seat 7, respectively; The pneumatic gripper 11 is fixed to the lower surface of the adjusting sleeve 29. By sliding the two first guide blocks 28 on the two first guide rails 8, the adjusting sleeve 29 can move along the direction of the two first guide rails 8. When it moves to a certain position, the two positioning bolts 30 are rotated to abut against the bearing seat 7, restricting the movement of the adjusting sleeve 29 on the bearing seat 7. This facilitates the adjustment of the distance between the two clamping parts 10 according to the part processing position and the placement position of the loading part, ensuring that the two clamping parts 10 can accurately adsorb and grip the parts at the processing position and loading position, and can easily and quickly adapt to parts of different sizes. The scale groove 31 can ensure the accuracy of the moving distance and position of the adjusting sleeve 29, avoiding the inaccurate movement position from affecting the adsorption and gripping effect of the two clamping parts 10 on the parts.

[0022] Optionally, the translation part 5 includes two second guide rails 32 symmetrically fixed to the front surface of the base 2, several second guide blocks 33 slidably mounted on the two second guide rails 32 and fixedly connected to the translation plate 3, a screw adjustment mechanism 34 disposed at one end of the base 2, two control gears 35 rotatably mounted on the base 2 and the screw adjustment mechanism 34, a control toothed belt 36 meshing and sleeved on the two control gears 35 and fixed to the translation plate 3, and a drive motor 37 mounted on the base 2; The output end of the drive motor 37 is fixedly connected to one of the control gears 35; In use, the drive motor 37 controls one of the control gears 35 to rotate, which in turn drives the other control gear 35 to rotate synchronously under the meshing transmission of the control belt 36. This allows the control belt 36 to drive the translation plate 3 to make stable horizontal linear motion under the cooperation of the two second guide rails 32 and several second guide blocks 33. The transmission cooperation of the gears and belts ensures the accuracy of movement, thereby improving the accuracy of the part loading and placement position.

[0023] Optionally, the lifting part 6 includes an electric push rod 38 fixed on the mounting base 4, a lifting seat 39 fixed to the telescopic end of the electric push rod 38 and placed below the mounting base 4, symmetrically fixed to the upper surface of the lifting seat 39, and both guide rods 40 passing through the mounting base 4. The support seat 7 is fixed to the lower surface of the lifting seat 39. When in use, the electric push rod 38 works and drives the support seat 7 to rise and fall through the lifting seat 39. The two guide rods 40 can effectively limit the movement trajectory of the lifting seat 39 and ensure that the lifting seat 39 drives the support seat 7 to move vertically without lateral deviation.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
