Description

Technical Field

[0001] This utility model relates to the field of workpiece conveying, and in particular to a loading and unloading assembly for valve sleeve processing. Background Technology

[0002] As a crucial component of the engine, valve sleeves require surface feature machining according to specific needs. Workpieces to be processed are typically placed in a storage tray, and to ensure storage density, they are usually positioned vertically. However, during processing, the workpieces need to be placed horizontally. Current feeding methods involve a robotic arm picking up workpieces one by one and moving them from the storage tray to the feeding position of the processing equipment. This method cannot keep up with the processing schedule, often resulting in the equipment waiting for workpieces to be placed, significantly reducing processing efficiency. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the main purpose of this utility model is to overcome the shortcomings of the prior art and disclose a loading and unloading assembly for valve sleeve processing, including a worktable and a positioning assembly, a first gripping assembly, a second gripping assembly, a first transfer assembly and two sets of second transfer assemblies disposed on the worktable;

[0004] The robotic arm arranges the workpieces within the positioning assembly. The first gripping assembly grips the workpieces within the positioning assembly and moves them to a second transfer assembly. The second transfer assembly then moves the workpieces to the feeding position. The workpieces processed by the processing equipment are placed on another second transfer assembly and moved horizontally using the second transfer assembly. The second gripping assembly grips the workpieces and feeds them into the first transfer assembly. The first transfer assembly then moves the workpieces to the unloading position.

[0005] Furthermore, the positioning component includes a positioning plate with a plurality of positioning holes arranged at intervals on the positioning plate, and one end of the workpiece is inserted into the positioning holes for placement.

The first actuator, the second actuator, and the sixth actuator drive the gripping mechanisms to move along the X-axis, Y-axis, and Z-axis, respectively.

[0007] Furthermore, the second gripping assembly includes a stand, a third actuator, a fourth actuator, and a clamping mechanism. The third actuator is mounted on the worktable via the stand, the fourth actuator is mounted on the third actuator, and the clamping mechanism is arranged on the fourth actuator. The third actuator and the fourth actuator drive the clamping mechanism to move along the Y-axis and Z-axis, thereby moving the workpiece processed on the second transfer assembly to the first transfer assembly.

[0008] Furthermore, the gripping mechanism includes a rotating finger cylinder and grippers mounted on the rotating finger cylinder.

[0009] Furthermore, the gripper includes a clamping block with a recessed positioning groove that matches the shape of the outer wall of the workpiece.

[0010] Furthermore, the second transplanting assembly includes a fixed base, a guide rail, a movable plate, a cylinder, and several workpiece seats. The guide rail is arranged parallel to both sides of the fixed base, the movable plate is slidably arranged on the guide rail, and the movable plate is driven by the cylinder to reciprocate along the Y-axis. The workpiece seats are arranged along the X-axis.

[0011] Furthermore, the first transplantation assembly includes a fifth actuator and a plurality of workpiece seats disposed on the fifth actuator, the fifth actuator driving the workpiece seats to move along the X-axis.

[0013] Furthermore, the end plate is provided with an inclined guide surface.

[0014] The beneficial effects achieved by this utility model are:

[0015] This invention achieves workpiece clamping and rotation through the configuration of a first gripping component and a second gripping component, enabling changes in the workpiece angle. Combined with a positioning component, this significantly improves loading and unloading efficiency. Furthermore, the positioning component positions the workpiece before the first gripping component clamps it, ensuring proper positioning between adjacent workpieces. Two sets of second transfer components are provided for loading and unloading respectively, further increasing loading and unloading speed. Positioning grooves are provided on the grippers to prevent workpieces from falling or shifting during clamping. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] A loading and unloading assembly for valve sleeve machining, such as Figure 1As shown, the system includes a worktable 1 and a positioning component 2, a first gripping component 3, a second gripping component 4, a first transfer component 5, and two sets of second transfer components 6 mounted on the worktable 1. The two sets of second transfer components 6 are arranged side-by-side on the worktable 1, and each set of second transfer components 6 drives the workpieces to be processed and the processed workpieces to move horizontally. The positioning component 2 is used to position the workpieces, ensuring they are arranged at equal intervals and heights. The first gripping component 3 grips the workpieces from the positioning component 2 and transfers them to one of the second transfer components 6, which then moves the workpieces to the feeding position. The workpieces are simultaneously fed into the processing equipment by the processing equipment's gripping mechanism. After processing, the workpieces are placed onto another second transfer component 6 by the processing equipment's gripping component, and then moved horizontally by the second transfer component 4 to the gripping position. The second gripping component 4 then grips the workpieces and transfers them into the first transfer component 5, which then moves the workpieces to the unloading position. The loading and unloading of the workpieces are performed by a robotic arm.

[0029] In one embodiment, such as Figures 1-9 As shown, the positioning component 2 includes a positioning plate 21 with a plurality of positioning holes 22 spaced apart on it. One end of the workpiece is inserted into the positioning hole for placement. By cleverly utilizing the features of the workpiece, the workpiece is positioned through the positioning holes 22, and the outer edge of the workpiece cooperates with the positioning plate 21 to achieve height positioning of the workpiece. This facilitates the first gripping component 3 to accurately and simultaneously feed multiple workpieces into the second transfer component 6.

[0030] In one embodiment, such as Figures 1-9 As shown, the first gripping assembly 3 includes a first actuator 31, a second actuator 32, a sixth actuator 33, and several gripping mechanisms 34. The first actuator 31 is mounted on the worktable 1, the second actuator 32 is mounted on the first actuator 31, the sixth actuator 33 is mounted on the second actuator 32, and the gripping mechanisms 7 are arranged on the sixth actuator 33. The first actuator 31, the second actuator 32, and the sixth actuator 33 drive the gripping mechanisms to move along the X and Y axes. The first actuator 31 can be a synchronous belt slide or a servo slide. The second actuator 32 and the third actuator 33 can be cylinders.

[0031] In one embodiment, such as Figures 1-9 As shown, the second gripping assembly 4 includes a stand 41, a third actuator 42, a fourth actuator 43, and a gripping mechanism 7. The third actuator 42 is mounted on the worktable 1 via the stand 41, the fourth actuator 43 is mounted on the third actuator 42, and the gripping mechanism 7 is arranged on the fourth actuator 43. The gripping mechanism 7 is driven by the third actuator 42 and the fourth actuator 43 to move along the Y-axis and Z-axis, thereby moving the workpiece processed on the second transfer assembly 6 to the first transfer assembly 5.

[0032] In one embodiment, such as Figures 1-9 As shown, the gripping mechanism 7 includes a rotary finger cylinder 71 and a gripper 72 mounted on the rotary finger cylinder 71. The rotary finger cylinder 71 controls the gripper 72 to grip the workpiece and can drive the workpiece to rotate, thereby changing the workpiece's orientation.

[0033] In the above embodiments, such as Figures 1-9 As shown, the gripper 72 includes a gripping block 721 with a recessed positioning groove 722. The positioning groove 722 fits the shape of the outer wall of the workpiece. The positioning groove 722 on the gripper 72 further positions the workpiece to ensure that the product is placed in the correct position.

[0034] In one embodiment, such as Figures 1-9 As shown, the second transfer assembly 6 includes a fixed base 61, guide rails 62, a movable plate 63, a cylinder 64, and several workpiece seats 8. Two guide rails 62 are arranged parallel to each other on the fixed base 61. The movable plate 63 is mounted on the guide rails 62 and is guided to move horizontally via the guide rails 62. The cylinder 64 is mounted on the fixed base 61 and connected to the movable plate 63, driving the movable plate 63 to reciprocate along the Y-axis. The workpiece seats 8 are arranged along the X-axis, allowing multiple workpieces to be placed simultaneously. The processing equipment's gripping mechanism simultaneously feeds several workpieces into the processing equipment for processing.

[0035] In one embodiment, such as Figures 1-9 As shown, the first transfer assembly 5 includes a fifth actuator 51 and a plurality of workpiece seats 8 disposed on the fifth actuator 51. The fifth actuator 51 drives the workpiece seats 8 to move along the X-axis.

[0036] In the above embodiments, such as Figures 1-9 As shown, the workpiece holder 8 includes two support blocks 81 and an end plate 82. The two support blocks 81 are spaced apart, and V-shaped grooves 811 are recessed on the support blocks 81. The end plates 82 are located on the sides of the support blocks 81. Because the outer wall of the workpiece is circular, the V-shaped grooves 81 can be used to position the workpiece, and the end plates at both ends can be used to position the workpiece axially. Since the workpiece holders 8 are arranged continuously, only one end plate 82 is needed between adjacent workpiece holders 8.

[0037] In the above embodiments, such as Figures 1-9 As shown, the end plate 82 is provided with inclined guide surfaces 821. The inclined guide surfaces 821 of the end plates 82 on both sides can guide the workpiece into the workpiece seat 8, playing an auxiliary guiding and positioning role, and ensuring accurate positioning when fed into the processing equipment.

[0038] When using this utility model, such as Figures 1-9As shown, a robotic arm simultaneously grips multiple workpieces and places them on the positioning assembly 2. The positioning assembly 2 uses its positioning plate 21 and positioning holes 22 to position the workpieces by spacing and height. Then, the first gripping assembly 3 simultaneously grips the workpieces from the positioning assembly 2, rotates them 90°, and moves them to the workpiece seat 8 of the second transfer assembly 6. The second transfer assembly 6 moves the workpiece seat to the feeding position, waiting for the gripping assembly of the processing equipment to feed the workpiece into the processing equipment. The workpieces processed in the processing equipment are placed into another second transfer assembly 6. The second transfer assembly 6 moves the workpieces towards the second gripping assembly 3, which grips the workpieces, rotates them horizontally by 90°, and places them on the first transfer assembly 5. The first transfer assembly 5 moves the processed workpieces to the unloading position, where the robotic arm clamps the workpieces and places them into the storage tray.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
