[0008] The claw body 6 is fixed on the claw seat and moves inward or outward with the claw seat. The outer wall of the claw body 6 is provided with a slot 60 that can accommodate the annular protrusion 71 of the inner wall of the annular insert 7. The bottom surface of the slot 60 is provided with a support surface 60b for contacting the bottom surface of the annular protrusion 71 and providing support.

[0009] Multiple elastic pressure rods 5 are evenly distributed around the axis of the gripper cylinder 3. The ends of the elastic pressure rods 5 can contact the end face of the annular insert 7 and cause the annular insert 7 to tend to move away from the gripper cylinder 3.

[0010] Furthermore, the number of elastic pressure rods 5 is the same as the number of claw bodies 6.

[0011] Furthermore, the lower end of the slot 60 is provided with a limiting protrusion 61, the top surface of the limiting protrusion 61 serves as the support surface 60b, and the outer end of the support surface 60b is connected to the side wall of the limiting protrusion 61 through an inclined surface 612.

[0012] Furthermore, the radial width of the support surface 60b is 0.5mm-2mm.

[0013] Furthermore, the top surface of the slot 60 is provided with a limiting surface 60a for contacting the top surface of the annular insert, and the radial width L1 of the limiting protrusion 61 is smaller than the radial width L2 of the limiting surface 60a.

[0014] Furthermore, the outer wall of the slot 60 is an arc-shaped surface and can fit into the inner wall of the annular protrusion 71.

[0015] Furthermore, the mounting base 1 has a plurality of pressure rod seats 4 evenly distributed circumferentially, and the ends of the pressure rod seats 4 are bent radially inward to form a mounting portion 43; the elastic pressure rod 5 includes a pressure rod body 51 and a compression spring 52, the pressure rod body 51 is slidably fitted on the mounting portion 43 and the sliding direction is parallel to the axial direction of the gripper cylinder 3, the lower end of the pressure rod body 51 extends radially outward to form a pressure block 511 for contacting the end face of the annular insert, and the compression spring 52 is sleeved on the pressure rod body 51 and located between the mounting portion 43 and the pressure block 511.

[0017] Furthermore, a bracket plate 2 is detachably mounted on the mounting base 1, and the gripper cylinder 3 and the elastic pressure rod 5 are mounted on the bracket plate 2.

[0018] Furthermore, the claw body 6 is a rod parallel to the axis of the gripper cylinder 3, and the cross-section of the rod is elliptical or racetrack-shaped.

This guarantees stability during movement, preventing wobbling or falling. Simultaneously, during unloading, the elastic pressure bar pushes the annular insert axially outward, smoothly disengaging it from the claw while simultaneously pushing and pressing it into its installation position, ensuring precise installation. The slot sidewall features a beveled structure that guides the annular insert to detach smoothly during release, preventing jamming and ensuring accurate placement. The device employs a narrow-width support surface structure, which improves unloading speed, reduces jamming risk, and ensures smooth detachment of the annular insert from the claw, achieving efficient and precise material placement. A limiting surface structure is incorporated, which contacts the end face of the annular insert, reducing the claw's travel distance, improving the gripping response speed, reducing energy consumption, and optimizing the overall workflow. This utility model insert clamp is compact and small in size, enabling rapid gripping and precise placement of the annular insert, ensuring proper insert installation, providing reliable quality assurance for casting products, improving production efficiency, and reducing manufacturing costs.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] See Figures 1-13 This utility model provides an insert clamp for picking up and placing annular inserts, specifically for gripping annular inserts on a conveyor line and installing them into the insert mounting position of a casting mold. The annular insert is circular in shape and has annular protrusions inside. (See reference...) Figure 13 It includes a mounting base 1, a gripper cylinder 3, a gripper body 6, and an elastic pressure rod 5.

[0036] Mounting base 1 serves as a mounting carrier for mounting the gripper cylinder 3 and the elastic pressure rod 5, and is also used for connecting to the robotic arm. In this embodiment, mounting base 1 includes a first plate 11 and a second plate 12. The first plate 11 is perpendicular to the second plate 12, and the two are fixedly connected to form an L-shaped structure. A reinforcing rib 13 is provided between the first plate 11 and the second plate 12 to improve the overall structural strength. The first plate 11 is used to mount the gripper cylinder 3 and the elastic pressure rod 5, and the second plate 12 is used to connect to the robotic arm.

[0037] The gripper cylinder 3 is fixed on the mounting base 1, specifically on the first plate 11. The gripper cylinder includes a gripper seat, which can move radially inward and outward. There are multiple gripper seats, which are evenly distributed circumferentially. The multiple gripper seats can move synchronously radially inward or radially outward to clamp or release. In this embodiment, the gripper cylinder 3 is a three-jaw cylinder, that is, it has three gripper seats. The three-jaw cylinder is prior art, so it will not be described in detail in this embodiment.

[0038] The number of claw bodies 6 is the same as the number of claw seats, and in this embodiment there are three. The three claw bodies 6 are fixed on the three claw seats respectively, and move inward or outward synchronously with the claw seats. A slot 60 is provided on the outer wall of the claw body 6 (the side facing away from the center). The slot 60 is horizontally set and extends to the edge of the claw body at both ends. It can accommodate the annular protrusion 71 on the inner wall of the annular insert 7 to be inserted, and then used to grasp the annular insert 7. A support surface 60b is provided on the bottom surface of the slot 60. The support surface 60b is used to contact the bottom surface of the annular protrusion 71, thereby achieving stable support for the annular insert during the grasping process and preventing it from slipping.

[0039] The outer wall of the slot 60 (the end opposite to the axis) is an arc-shaped surface, which serves as the working surface (clamping surface) and can fit against the inner wall of the annular protrusion 71. A limiting protrusion 61 is provided at the lower end of the slot 60 (the end opposite to the gripper cylinder). The top surface of this limiting protrusion 61 forms a support surface 60b, used to support the annular insert during gripping. The plane containing this support surface 60b is perpendicular to the axis of the gripper cylinder, ensuring the coaxiality of the annular insert with the gripper cylinder during gripping and improving gripping and placement accuracy. The outer end of the support surface 60b... (The end facing away from the center) is connected to the side wall of the limiting protrusion 61 via the inclined surface 612, which is used to guide the annular insert to disengage smoothly during release, avoid jamming, and ensure the precise placement of the annular insert. The angle between the inclined surface 612 and the axis of the gripper cylinder is 30 degrees to 60 degrees. Since the annular protrusion on the inner wall of the annular insert is circular, the clamping surface of the slot 60, the limiting protrusion 61, and the inclined surface 612 are all designed as corresponding arcs to perfectly fit the annular protrusion 71 and ensure stability and accuracy during the gripping process.

[0040] To improve the efficiency and stability of material unloading (discharging), in this embodiment, the radial width of the support surface 60b is 0.5mm-2mm. When the claw body 6 moves inward by 0.5mm-2mm, the support surface 60b disengages from the annular protrusion on the inner wall of the annular insert 7 and enters the inclined position. Under the action of the inclined surface and the elastic pressure rod, the annular insert 7 is pushed to move axially outward. This can improve the unloading speed, reduce the risk of jamming, and ensure that the annular insert 7 smoothly disengages from the claw body 6, thereby achieving efficient and accurate material placement.

[0041] A limiting surface 60a is provided on the top surface of the slot 60. This limiting surface 60a is used to contact the top surface of the annular insert and achieve limiting. In this embodiment, the radial width L1 of the limiting protrusion 61 is smaller than the radial width L2 of the limiting surface 60a. (See reference...) Figures 9-10 With the above structural design, the claw body only needs to be moved to the limit protrusion so that it can be engaged in the inner hole of the annular insert 7 and extend into the annular insert 7. When the limit surface 60a on the slot contacts the end face of the annular insert 7, it indicates that the axial position is in place. At this time, the claw body 6 moves outward so that the annular protrusion on the inner wall of the annular insert is engaged in the slot 60. At the same time, through the action of the elastic pressure rod, the annular insert 7 is axially pressed against the support surface 60b, resulting in high gripping efficiency, accuracy and reliability. At the same time, it can reduce the movement stroke of the claw body 6, improve the response speed of the gripping operation, reduce energy consumption and optimize the overall workflow.

[0042] In this application, the claw body 6 is a rod parallel to the axis of the gripper cylinder 3, and the cross-section of the rod is elliptical or racetrack-shaped, which facilitates the reduction of the overall volume, makes it easy to extend into the installation position, and ensures structural strength.

[0043] Multiple elastic pressure rods 5 are evenly distributed circumferentially around the axis of the gripper cylinder 3. In this embodiment, the number of elastic pressure rods 5 is the same as the number of gripper bodies 6. They are located on the side close to the gripper body 6. The end of the elastic pressure rod 5 can contact the end face of the annular insert 7. At the same time, under the action of elasticity, the annular insert 7 tends to move away from the gripper cylinder 3. That is, the elastic pressure rod 5 can push the annular insert 7 to move axially outward (away from the gripper cylinder). During the gripping process, under the action of the elastic pressure rod 5, the annular insert 7 can be pushed to move axially outward, and the bottom surface of the annular protrusion on the inner wall of the annular insert 7 is tightly attached to the support surface 60b to ensure stability during movement and prevent shaking or falling. On the other hand, when the material is unloaded, that is, when the gripper body 6 separates from the annular insert 7, the elastic pressure rod 5 pushes the annular insert 7 to move axially outward, so that the annular insert 7 can smoothly detach from the gripper body 6, and at the same time push it in and press it into the installation position of the insert to ensure that the annular insert is accurately installed and installed in place.

[0044] In this embodiment, a pressure rod seat 4 is installed on the mounting base 1. There are multiple pressure rod seats 4, preferably three. The three pressure rod seats 4 are evenly distributed around the axis of the gripper cylinder. The pressure rod seat 4 is a rod-shaped structure with its length direction parallel to the axis of the gripper cylinder. The end of the pressure rod seat 4 is bent radially inward to form a mounting part 43. A guide hole is passed through the mounting part 43. The axis of the guide hole is parallel to the axis of the gripper cylinder and is used to install the elastic pressure rod 5.

[0045] The elastic pressure rod 5 includes a pressure rod body 51 and a compression spring 52. The pressure rod body 51 is a cylindrical rod that slides on the mounting part 43, specifically, it slides in the guide hole. Its sliding direction is parallel to the axial direction of the gripper cylinder 3. The lower end (facing away) of the pressure rod body 51 extends radially outward with its own axis as a reference to form a pressure block 511. The pressure block 511 is cylindrical and is used to contact the end face of the annular insert and to push the annular insert 7 to move axially, or to make the annular insert 7 tend to move axially. The diameter of the pressure block 511 is slightly larger than the diameter of the pressure rod body 51. Therefore, when the pressure block 51... The top surface of 1 forms a stepped surface to support the compression spring; the compression spring 52 is sleeved on the outside of the pressure rod body 51 and is located between the mounting part 43 and the pressure block 511, that is, one end of the compression spring 52 contacts the end face of the mounting part 43 and the other end contacts the end face of the pressure block 511, thereby causing the pressure rod body 51 to have a tendency to move away from the gripper cylinder; a limit washer is fixed at the other end of the pressure rod body 51 by bolt 53. The diameter of the limit washer is larger than the diameter of the pressure rod body 51 and is used to limit the pressure rod body 51. When it is unloaded, under the action of the compression spring, the limit washer contacts the mounting part 43.

[0046] To reduce processing costs and improve the operational reliability and service life of the elastic pressure rod 5, this application provides a mounting hole on the mounting part 43. The mounting hole is a stepped hole, and a guide sleeve 44 is embedded in the mounting hole. The guide sleeve 44 is annular with guide holes through both ends. The pressure rod body 51 is slidably fitted in the guide holes of the guide sleeve 44. This not only improves the operating accuracy of the elastic pressure rod 5, but also provides good wear resistance, facilitates later maintenance, and reduces manufacturing and usage costs.

[0047] This application also includes a bracket plate 2, which is detachably mounted on the mounting base 1 by bolts, and the gripper cylinder 3 and the elastic pressure rod 5 are mounted on the bracket plate 2. The above arrangement facilitates overall assembly and subsequent maintenance.

[0048] This utility model insert clamp features an elastic pressure bar structure that pushes the annular insert axially outward, ensuring a tight fit between the bottom surface of the annular protrusion and the supporting surface. This guarantees stability during movement, preventing wobbling or falling. Simultaneously, during unloading, the elastic pressure bar pushes the annular insert axially outward, smoothly disengaging it from the claw while simultaneously pushing and pressing it into its installation position, ensuring precise installation. The slot sidewall features a beveled structure that guides the annular insert to detach smoothly during release, preventing jamming and ensuring accurate placement. The device employs a narrow-width support surface structure, which improves unloading speed, reduces jamming risk, and ensures smooth detachment of the annular insert from the claw, achieving efficient and precise material placement. A limiting surface structure is incorporated, which contacts the end face of the annular insert, reducing the claw's travel distance, improving the gripping response speed, reducing energy consumption, and optimizing the overall workflow. This utility model insert clamp is compact and small in size, enabling rapid gripping and precise placement of the annular insert, ensuring proper insert installation, providing reliable quality assurance for casting products, improving production efficiency, and reducing manufacturing costs.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
