Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and more specifically, to a composite clamping fixture and a material conveying device. Background Technology
[0002] Currently, some products require the embedding of metal contacts in their die-cast housings for convenient charging connections. These die-cast housings are typically made of cast aluminum, and metal sheets need to be pre-embedded in the casting mold during the die-casting process. Multiple metal sheets need to be installed at once. If installed manually, these sheets must be placed into the casting mold sequentially. Due to the high temperature of the casting mold, the first sheets placed will warp and deform under the high temperature, significantly increasing the defect rate and reducing production efficiency. Furthermore, the die-casting process involves high operating temperatures and a harsh environment, making manual installation of the metal sheets highly dangerous. Utility Model Content
[0003] This utility model provides a composite fixture and a material conveying device to solve the problems of high defect rate, high risk and low production efficiency caused by manually placing metal sheets and other workpieces into casting molds in the prior art.
[0004] To address the aforementioned problems, according to one aspect of this utility model, a composite fixture is provided, comprising: a support frame having opposing first and second support plates; an adsorption fixture mounted on the first support plate, the adsorption fixture including a plurality of adsorption heads, each adsorption head being used to adsorb a workpiece; and a clamping fixture mounted on the second support plate, the clamping fixture including a plurality of openable and closable grippers for picking up and placing products.
[0005] Furthermore, the adsorption head includes a rod body and two limiting plates disposed at the end of the rod body. The rod body has a hollow structure, and the two limiting plates are spaced apart. The end of the rod body is used to adsorb the workpiece, and the two limiting plates are in a limiting fit with the workpiece.
[0006] Furthermore, the end of the rod has a mating groove located between two adsorbed workpieces, and the shape of the mating groove matches the shape of the protrusion on the workpiece; the limiting plate is arc-shaped to match the side wall of the workpiece, and the part of the workpiece not adsorbed extends out from the gap between the two limiting plates.
[0007] Furthermore, the adsorption fixture also includes multiple linear bearings mounted on the first support plate, with each adsorption head axially movable through the linear bearings.
[0008] Furthermore, each adsorption head can move axially through the first support plate. The adsorption fixture also includes a drive unit, which is mounted on the first support plate and located between the first and second support plates. The drive unit drives multiple adsorption heads to move synchronously.
[0009] Furthermore, the drive unit includes a drive cylinder and a drive plate. The drive cylinder is mounted on the first support plate, and the cylinder rod of the drive cylinder is drivenly connected to the drive plate. The end of the adsorption head near the second support plate is connected to the drive plate.
[0010] Furthermore, the clamping fixture also includes a picking cylinder, a movable rod, and a spring. The picking cylinder drives multiple grippers to open and close. The ends of the picking cylinder and the movable rod are connected. The movable rod can move axially through the second support plate. The spring is sleeved on the movable rod, and the two ends of the spring abut against the picking cylinder and the second support plate, respectively.
[0011] Furthermore, the composite fixture also includes a vision recognition component mounted on a support frame, which is used to identify the position of the workpiece.
[0012] Furthermore, the support frame also includes a first connecting plate, a second connecting plate, and a flange. The first connecting plate and the second connecting plate are arranged in parallel. The first connecting plate is connected to both the first support plate and the second support plate.

[0013] According to another aspect of the present invention, a material conveying device is provided, which includes a material conveying robot and the aforementioned composite clamp, wherein the composite clamp is installed at the moving end of the material conveying robot.
[0014] In this solution, the support frame provides an installation platform for the adsorption fixture and the clamping fixture. The adsorption fixture has multiple adsorption heads, each capable of adsorbing one workpiece, allowing for the simultaneous adsorption of multiple workpieces. This facilitates the simultaneous placement of multiple workpieces into the casting mold during subsequent processes, avoiding the problem of warping and deformation caused by high temperatures due to different placement times, thus significantly improving production efficiency. The grippers on the clamping fixture can transfer the finished casting product, improving the stability of gripping and operational safety. Through automated adsorption and clamping operations, multiple workpieces are simultaneously embedded into the casting mold, and the finished casting product is transferred, effectively avoiding the high defect rate problem when placing workpieces sequentially, improving product production efficiency.

[0026] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.
[0027] like Figures 1 to 5 As shown, an embodiment of this utility model provides a composite fixture, including: a support frame 10, the support frame 10 having a first support plate 11 and a second support plate 12 opposite to each other; an adsorption fixture 20, installed on the first support plate 11, the adsorption fixture 20 including a plurality of adsorption heads 21, each adsorption head 21 being used to adsorb a workpiece; and a clamping fixture 30, installed on the second support plate 12, the clamping fixture 30 including a plurality of openable and closable grippers 31 for picking up and placing products.
[0028] In this solution, the support frame 10 provides an installation platform for the adsorption fixture 20 and the clamping fixture 30. The adsorption fixture 20 has multiple adsorption heads 21, each of which can adsorb one workpiece, enabling the simultaneous adsorption of multiple workpieces. This facilitates the simultaneous placement of multiple workpieces into the casting mold during subsequent processes, avoiding the problem of bending and deformation of workpieces placed earlier due to high temperatures caused by different placement times, thus greatly improving production efficiency. The grippers 31 on the clamping fixture 30 can transfer the cast product, improving the stability of gripping and the safety of operation. Through automated adsorption and clamping operations, multiple workpieces are simultaneously embedded into the casting mold and the cast product is transferred, effectively avoiding the problem of high defect rates when placing workpieces sequentially, improving product production efficiency. At the same time, automated operation reduces labor costs and ensures the personal safety of operators.
[0029] like Figure 4 and Figure 5 As shown, the adsorption head 21 includes a rod 211 and two limiting plates 212 disposed at the ends of the rod 211. The rod 211 has a hollow structure, and the two limiting plates 212 are spaced apart. The ends of the rod 211 are used to adsorb workpieces, and the two limiting plates 212 are in a limiting fit with the workpieces. The hollow structure of the rod 211 creates a negative pressure state inside, which firmly adsorbs the workpieces to the ends of the rod 211. The limiting plates 212 are in a limiting fit with the workpieces, ensuring the orientation of the workpieces and facilitating matching with the shape of the casting mold in subsequent processes.
[0030] In this embodiment, the end of the rod 211 has a mating groove 2111, which is located between two adsorbed workpieces. The shape of the mating groove 2111 matches the shape of the protrusion on the workpiece. The limiting plate 212 is arc-shaped to match the side wall of the workpiece, and the unadsorbed part of the workpiece protrudes from the notch between the two limiting plates 212. The mating groove 2111 and the limiting plate 212 respectively match the protrusion on the workpiece and the arc-shaped protruding side wall of the workpiece, improving the stability of workpiece adsorption and the accuracy of workpiece positioning.
[0031] like Figure 1 and Figure 3 As shown, the adsorption fixture 20 also includes multiple linear bearings 22, which are mounted on the first support plate 11. Each adsorption head 21 can move axially through the linear bearing 22. By setting the linear bearings 22, sliding friction is reduced, allowing the adsorption head 21 to move smoothly in the axial direction. This improves the operational flexibility and response speed of the adsorption fixture 20, reduces wear and energy consumption of the adsorption head 21 during movement, and helps extend the service life of each component.
[0032] like Figure 1 and Figure 2 As shown, each adsorption head 21 can move axially through the first support plate 11. The adsorption fixture 20 also includes a drive unit 23, which is mounted on the first support plate 11 and located between the first support plate 11 and the second support plate 12. The drive unit 23 drives multiple adsorption heads 21 to move synchronously. By uniformly controlling the movement of multiple adsorption heads 21 through the drive unit 23, multiple workpieces can be simultaneously adsorbed and released, improving the production efficiency of the composite fixture.
[0033] like Figure 1 As shown, the drive unit 23 includes a drive cylinder 231 and a drive plate 232. The drive cylinder 231 is mounted on the first support plate 11, and the cylinder rod of the drive cylinder 231 is drivenly connected to the drive plate 232. The end of the adsorption head 21 near the second support plate 12 is connected to the drive plate 232. Under the drive of the drive plate 232, the adsorption head 21 can extend and retract axially, facilitating the adsorption of workpieces. The drive plate 232 also limits the axial extension and retraction of the adsorption head 21. The drive cylinder 231 provides power for the axial extension and retraction of the adsorption head 21.
[0034] In this embodiment, the clamping fixture 30 further includes a picking cylinder 32, a movable rod 33, and a spring 34. The picking cylinder 32 drives multiple grippers 31 to open and close. The ends of the picking cylinder 32 and the movable rod 33 are connected. The movable rod 33 can move axially through the second support plate 12. The spring 34 is sleeved on the movable rod 33, and its two ends abut against the picking cylinder 32 and the second support plate 12, respectively. By using the picking cylinder 32 to drive the grippers 31 to open and close, and through the cooperation of the movable rod 33 and the spring 34, the cast product can be stably clamped, improving the efficiency and stability of product removal. The spring 34 provides a buffer for the drive transmission between the components, avoiding product damage that may be caused by hard collisions.
[0035] In this embodiment, the composite fixture also includes a vision recognition component 40, which is mounted on the support frame 10 and is used to identify the position of the workpiece. By utilizing vision recognition technology, the position and status of the workpiece are monitored in real time, ensuring the precise operation of the composite fixture, improving the accuracy and stability of the operation, and reducing production errors caused by workpiece position deviations.
[0036] In this embodiment, the support frame 10 further includes a first connecting plate 13, a second connecting plate 14, and a flange 15. The first connecting plate 13 and the second connecting plate 14 are arranged in parallel. The first connecting plate 13 is connected to both the first support plate 11 and the second support plate 12, and the second connecting plate 14 is connected to both the first support plate 11 and the second support plate 12. The vision recognition component 40 is mounted on the first connecting plate 13, and the flange 15 is mounted on the second connecting plate 14. The arrangement of the first connecting plate 13 and the second connecting plate 14 provides a stable mounting position for the vision recognition component 40 and the flange 15, while optimizing the overall structural layout of the composite fixture, improving the stability of the composite fixture connection and the flexibility of operation. The vision recognition component 40 enhances the stability and accuracy of the device, and the flange 15 simplifies the connection steps between the composite fixture and other equipment, thereby improving production efficiency.
[0037] An embodiment of this utility model also provides a material conveying device, which includes a material conveying robot and the aforementioned composite clamp, with the composite clamp mounted on the moving end of the material conveying robot. By combining the composite clamp with the material conveying robot, and utilizing the mobility of the material conveying robot and the gripping performance of the composite clamp, automatic loading and unloading of workpieces is achieved, significantly improving the efficiency of automated production lines, reducing labor costs, and enhancing production safety and continuity.
