Description

Technical Field

[0001] This invention belongs to the field of lost-wax casting technology, and more specifically, relates to a slurry-coating and sand-spraying device for a robotic arm. Background Technology

[0002] Lost-wax casting generally refers to precision casting. Precision casting is a general term for processes that produce castings with precise dimensions. Compared to traditional sand casting, precision casting produces castings with more accurate dimensions and better surface finish. It is a casting method that uses a fusible primary model to form the casting, where the primary model is the wax pattern. In the lost-wax casting process, a suitable pattern material (such as paraffin wax) is selected to create the pattern. Refractory slurry is repeatedly applied to the pattern, and refractory sand is sprinkled on it. Subsequently, the shell hardens and dries. The internal pattern is melted to obtain the cavity, and the shell is fired to obtain sufficient strength. The required metal material is then poured in. After solidification and cooling, the shell is removed and the sand is cleaned to obtain a high-precision finished product.

[0003] During the slurry dipping and sand rinsing process, the cover plate on a wax tree is usually threaded to the upright of the slurry dipping and sand rinsing device. The wax tree is then directly placed into the slurry tank by a robotic arm, and slurry that can submerge the wax tree is injected, allowing the wax tree to be dipped in the slurry tank. After that, the wax tree is rotated and sand is evenly rinsed. This method can only dip and rinse one wax tree at a time, resulting in low work efficiency. Summary of the Invention

[0004] This invention provides a slurry-dipping and sand-sprinkling device for robotic arms, which can simultaneously slurry-dipped and sand-sprinkled multiple wax trees, thereby improving work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A slurry-coating and sand-spraying device for a robotic arm is provided, comprising a support frame, a connector, and a locking block. The support frame is equipped with a downwardly extending upright for gripping by the robotic arm. The outer periphery of the upright has several circumferentially spaced, horizontally extending elongated plates. The connector penetrates the elongated plates vertically and is rotatably connected to them. The connector is positioned near the outer end of the elongated plates, and its lower end is threaded to a cover plate of a wax tree. The upper outer periphery of the connector has an outwardly opening locking groove. The locking block is slidably connected to the elongated plates along their direction, and can engage in the locking groove to lock the circumferential outer periphery of the connector.

[0006] In one possible implementation, the upright is slidably connected to a slider along the axial direction. The slider is connected to the locking block via a hinge rod, with both ends of the hinge rod hinged to the slider and the locking block respectively. The slider can move downward to cause the locking block to engage in the locking groove.

[0007] In some embodiments, the upright is fitted with an elastic element for elastically pushing the slider upwards, the elastic element being located below the slider.

[0008] In some embodiments, the upper end of the upright is provided with a hanging platform whose cross-sectional area gradually decreases from top to bottom, and the support frame is provided with a limiting clip with an opening facing one side and extending vertically. The limiting clip gradually closes from top to bottom to accommodate and suspend the hanging platform.

[0009] In some embodiments, a sliding sleeve is slidably fitted onto the upright, the sliding sleeve being located above the slider and used to push the slider downwards.

[0010] In some embodiments, the outer peripheral wall of the upright is provided with a sliding groove extending axially along the upright, and the inner peripheral wall of the sliding sleeve is provided with a sliding strip extending axially along the sliding sleeve. The sliding strip is located in the sliding groove, and the upper end of the sliding strip is provided with a limiting sleeve for engaging with the lower outer periphery of the limiting card.

[0011] In one possible implementation, the outer peripheral wall of the upper end of the connector is provided with a plurality of circumferentially spaced and horizontally outwardly extending extension arms, and the locking groove is formed between two adjacent extension arms. The outer end of the extension arm has an outwardly protruding arc-shaped transition portion.

[0012] In some embodiments, the opening width of the locking groove gradually increases, and the locking block has a retractable portion on the side near the connector that can be engaged in the locking groove.

[0013] In one possible implementation, the connector is threaded with a locking nut located below the elongated plate, the top surface of which can abut against the bottom wall of the elongated plate.

[0014] In one possible implementation, the lower end of the pole is provided with a mounting plate whose surface extends horizontally, and the long strip is connected to the upper surface of the mounting plate.

[0015] The slurry-dipping and sand-sprinkling device for robotic arms provided in this embodiment, compared with the prior art, uses multiple wax trees and multiple connecting parts connected one-to-one by threaded connections. By rotating the connecting parts, the opening direction of the locking groove is made to face the locking block. Then, the locking block is slid into the locking groove to restrict the circumferential rotation of the connecting parts. Under the grip of the robotic arm on the upright, multiple wax trees are simultaneously driven to perform slurry-dipping and sand-sprinkling, which improves work efficiency.

[0026] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention 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 merely illustrative of the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0028] Please see Figures 1 to 7 The present invention will now describe the slurry-coating and sand-spraying device for a robotic arm. The slurry-coating and sand-spraying device for a robotic arm includes a support frame 10, a connector 40, and a locking block 50. The support frame 10 is equipped with a downwardly extending upright 20 for gripping by the robotic arm. The outer peripheral wall of the upright 20 is provided with a plurality of circumferentially spaced and horizontally extending elongated plates 30. The connector 40 is disposed through the elongated plates 30 in the vertical direction and is rotatably connected to the elongated plates 30. The connector 40 is disposed near the outer end of the elongated plates 30. The lower end of the connector 40 is used for threaded connection with the cover plate of a wax tree. The upper outer periphery of the connector 40 is provided with a locking groove 41 with an outward opening. The locking block 50 is slidably connected to the elongated plates 30 along the direction of the elongated plates 30. The locking block 50 can be engaged in the locking groove 41 to lock the circumferential outer periphery of the connector 40.

[0029] This application provides a robotic arm device for applying slurry and sanding. In actual use, the upright 20 is hung on the support frame 10, with the locking block 50 at the end away from the connector 40. Multiple wax trees are threadedly connected to multiple connectors 40 one by one. The connector 40 is rotated so that the opening of the locking groove 41 faces the locking block 50. Then, the locking block 50 is slid into the locking groove 41 to restrict the circumferential rotation of the connector 40. The robotic arm grabs the upright 20 and drives the wax trees into the slurry tank for slurry application, and then into the sanding machine for uniform sanding. This not only allows for simultaneous slurry application and sanding of multiple wax trees, improving work efficiency, but also avoids the free rotation of the connector 40 from affecting the sanding effect.

[0030] Because the robotic arm needs to hold the upright 20 in a horizontal position during the sand-spraying process and rotate the upright 20 circumferentially to evenly spray sand onto the wax tree, the locking block 50 prevents the wax tree from rotating and affecting the sand-spraying effect.

[0031] Compared with the prior art, the slurry-coating and sand-spraying device for robotic arms provided in this embodiment uses multiple wax trees and multiple connecting parts 40 connected one-to-one by threaded connections. By rotating the connecting parts 40, the opening direction of the locking groove 41 is made to face the locking block 50. Then, the locking block 50 is slid into the locking groove 41 to restrict the circumferential rotation of the connecting parts 40. Under the gripping of the robotic arm on the upright 20, the multiple wax trees are simultaneously driven to coat with slurry and spray with sand, which improves work efficiency.

[0032] Furthermore, the long strip 30 is provided with a sliding groove 31 that extends radially along the upright 20 and opens upward, and the locking block 50 is slidably connected in the locking groove 41.

[0033] Optionally, an insert is provided through the long strip 30 along the extension direction perpendicular to the long strip 30. The insert is horizontally arranged and slidably connected to the long strip 30. The insert is used to abut against the side of the locking block 50 away from the connector 40 to lock the position of the locking block 50.

[0034] Optionally, a tightening bolt is provided through the locking block 50 along the vertical direction and is threadedly connected to the locking block 50. The inner end of the tightening bolt is used to abut against the top wall of the long strip plate 30 to lock the position of the locking block 50.

[0035] In one possible implementation, the aforementioned pole 20 adopts the following... Figures 1 to 3 and Figures 5 to 7 The structure shown is described in the following document. Figure 1 , Figure 2 and Figures 4 to 6The upright 20 is slidably connected to a slider 70 along the axial direction. The slider 70 is connected to the locking block 50 through a hinge rod 71. The two ends of the hinge rod 71 are respectively hinged to the slider 70 and the locking block 50. The slider 70 can move down to drive the locking block 50 to engage in the locking groove 41.

[0036] Specifically, the two ends of the hinge rod 71 are respectively hinged to the top of the locking block 50 and the side wall of the slider 70 away from the upright rod 20. When installing the wax tree, first move the locking block 50 away from the connector 40 to remove the restriction on the connector 40. At this time, the slider 70 moves upward under the drive of the hinge rod 71. Then, the worker rotates the connector 40 to make the cover plate on the wax tree threadedly connected to the connector 40, and aligns the locking groove 41 with the locking block 50. Finally, the locking block 50 is released, and the slider 70 slides downward under the action of gravity, pushing the locking block 50 into the locking groove 41, thereby limiting the connector 40. Finally, the robot arm grips the upper part of the upright 20 of the slider 70 and makes the robot arm contact the top of the slider 70. The robot arm drives the wax tree into the slurry tank for slurry application, and then into the sand-spraying machine for rotation and uniform sand application. Under the limitation of the robot arm, the slider 70 is prevented from sliding upward to the upright 20, thereby limiting the separation of the locking block 50 from the locking groove 41, achieving stable limitation of the connector 40, and ensuring the limiting effect of the locking block 50 on the connector 40.

[0037] In some embodiments, the upright 20 is fitted with an elastic element 60 for elastically pushing the slider 70 upward, and the elastic element 60 is located below the slider 70.

[0038] Specifically, during the installation of the wax tree, the slider 70 slides upward under the push of the elastic element 60, causing the locking block 50 to move away from the connector 40, thus releasing the restriction on the connector 40. Then, the operator rotates the connector 40 to make the cover plate on the wax tree threadedly connected to the connector 40, and aligns the locking groove 41 with the locking block 50. Finally, the locking block 50 is released, and the robot arm wraps around the outer periphery of the upper part of the upright 20 above the slider 70 (without clamping the upright 20), and slides down to push the slider 70. The slider 70 moves downward and compresses the elastic element 60. The slider 70 pushes the locking block 50 into the locking groove 41 through the hinge rod 71. At this time, the robot arm grips the upright 20 and removes the upright 20 from the support frame 10. Under the restriction of the robot arm, the locking block 50 is always in the locking groove 41 to stably limit the connection 40. After the wax tree is coated with sap and sanded, the upright 20 is reattached to the support frame 10. The robot arm leaves the support, which releases the restriction on the slider 70. The compressed elastic element 60 extends and pushes the slider 70 upward. The slider 70 drives the locking block 50 to move away from the locking groove 41, thereby automatically releasing the restriction on the connector 40. This avoids the tedious process of manually releasing the restriction on the connector 40 and improves work efficiency.

[0039] Furthermore, a mounting platform 22 is provided on the outer peripheral wall of the upright 20, located below the slider 70. The elastic element 60 is connected to the mounting platform 22 and the slider 70 respectively. The mounting platform 22 facilitates the installation of the elastic element 60, and provides a certain gap between the elastic element 60 and the upright 20, preventing the upright 20 from interfering with the extension and retraction of the elastic element 60, and ensuring the effectiveness of the elastic element 60.

[0040] In some embodiments, the upper end of the upright 20 is provided with a hanging platform 21 whose cross-sectional area gradually decreases from top to bottom, and the support frame 10 is provided with a limiting card 11 with an opening facing one side and extending vertically. The limiting card 11 gradually retracts from top to bottom to accommodate and suspend the hanging platform 21.

[0041] Specifically, the diameter of the upright 20 is smaller than the minimum distance between the two opposite sidewalls at the opening of the limiting card 11, meaning the upright 20 can horizontally enter and exit the limiting card 11. First, a portion of the hanging platform 21 is positioned above the limiting card 11. The upright 20 is then moved horizontally into the limiting card 11, and then lowered so that the hanging platform 21 is embedded into the inner cavity of the limiting card 11 from above. The inner wall of the limiting card 11 and the outer peripheral wall of the hanging platform 21 abut against each other, thus achieving stable attachment of the upright 20 to the support frame 10. In use, a robotic arm grasps the upright 20 and moves it upwards a certain distance, then moves the hanging platform 21 out of the opening of the limiting card 11, facilitating the attachment and removal of the upright 20.

[0042] It should be noted that after the opening of the limit card 11 is set, it is more than half the size of the limit card 11 without an opening. Therefore, the upright 20 cannot be separated from the limit card 11 by moving it horizontally outward from the opening.

[0043] Furthermore, the top of the support frame 10 is provided with two welding strips 12 spaced apart, and the limiting card 11 is set inside the two welding strips 12. The outer peripheral wall of the limiting card 11 is welded to the two opposite side walls of the welding strips 12 respectively, which facilitates the installation of the limiting card 11.

[0044] In some embodiments, a sliding sleeve 90 is slidably fitted on the upright 20, the sliding sleeve 90 being located above the slider 70 and used to push the slider 70 downward.

[0045] Specifically, the sliding sleeve 90 slides in conjunction with the upright 20 in the vertical direction. Since there are multiple long strips 30, each long strip 30 has a corresponding connecting piece 40. Therefore, the number of sliders 70 slidably connected on the upright 20 is the same as the number of long strips 30. The multiple sliders 70 are arranged at intervals around the circumference of the upright 20. With the setting of the sliding sleeve 90, as long as the robot arm surrounds the outer circumference of the upright 20 above the sliding sleeve 90 and moves downward to push the sliding sleeve 90, the sliding sleeve 90 can push multiple sliders 70 downward at the same time. This avoids the situation where the irregularly shaped robot arm cannot push down multiple sliders 70 at the same time, and ensures that multiple connecting pieces 40 are simultaneously limited.

[0046] In some embodiments, the outer peripheral wall of the upright 20 is provided with a sliding groove 23 extending axially along the upright 20, and the inner peripheral wall of the sliding sleeve 90 is provided with a sliding strip 92 extending axially along the sliding sleeve 90. The sliding strip 92 is located in the sliding groove 23, and the upper end of the sliding strip 92 is provided with a limiting sleeve 91 for engaging with the lower outer periphery of the limiting card 11.

[0047] Specifically, the slide bar 92 is designed to connect the sliding sleeve 90 and the limiting sleeve 91, and the slide bar 92 is located within the sliding groove 23, that is, the slide bar 92 is embedded within the upright 20, thus preventing interference between the robotic arm and the slide bar 92 when the robotic arm grips the upright 20. The limiting sleeve 91 is fitted onto the outer periphery of the limiting card 11 to further limit the upright 20, ensuring that the upright 20 is stably positioned within the limiting card 11 and preventing the upright 20 from falling.

[0048] The robotic arm surrounds the outer periphery of the upright 20 between the sliding sleeve 90 and the limiting sleeve 91, and slides down to push the sliding sleeve 90. The sliding bar 92 drives the limiting sleeve 91 to move downward. The limiting sleeve 91 leaves the limiting card 11, releasing the limitation on the hanging platform 21. The sliding sleeve 90 pushes the slider 70 downward and compresses the elastic element 60. The slider 70 pushes the locking block 50 into the locking groove 41 through the hinge rod 71. At this time, the robotic arm grips the upright 20 and removes the upright 20 from the support frame 10. Under the limitation of the robotic arm, the locking block 50 is always in the locking groove 41 to stably limit the connection 40. After the wax tree is dipped in slurry and sanded, the hanging platform 21 is reattached to the limiting card 11. The robot arm leaves the upright 20, releasing the restriction on the slider 70. The compressed elastic element 60 extends and pushes the slider 70 upward. The slider 70 drives the locking block 50 to move away from the locking groove 41, thereby automatically releasing the restriction on the connecting piece 40. The slider 70 also pushes the sliding sleeve 90 upward, so that the limiting sleeve 91 is fitted onto the outer periphery of the limiting card 11, thereby limiting the hanging platform 21. This not only allows the restriction on the hanging platform 21 and the connection piece 40 to be released separately by the downward movement of the robot arm during use, but also automatically limits the hanging platform 21 and releases the lock on the connection piece 40 when the robot arm leaves, improving work efficiency.

[0049] Furthermore, the lower end of the limiting sleeve 91 is provided with an inwardly protruding abutment platform 93. The upper surface of the abutment platform 93 is used to abut against the lower surface of the limiting card 11, and the upper end of the slide bar 92 is connected to the inner peripheral wall of the abutment platform 93. Through the abutment between the abutment platform 93 and the lower end of the limiting card 11, the position of the limiting sleeve 91 is limited in a timely manner to prevent the limiting sleeve 91 from sliding excessively upward.

[0050] Furthermore, the sliding groove 23 extends downward to the lower part of the elastic member 60, and the slider 70 is slidably connected in the sliding groove 23, so that the slider 92 and the corresponding slider 70 share a sliding groove 23, avoiding the need to open extra grooves on the upright 20, reducing processing costs and efficiency.

[0051] In one possible implementation, the aforementioned connector 40 adopts, as shown in... Figure 1 and Figure 4 The structure shown is described in the following document. Figure 1 and Figure 4 The outer peripheral wall of the upper end of the connector 40 is provided with a number of circumferentially spaced and horizontally outward extension arms 42, and a locking groove 41 is formed between two adjacent extension arms 42. The outer end of the extension arm 42 has an outwardly protruding arc-shaped transition portion 421.

[0052] Specifically, the extension arm 42 is located above the long strip 30 and is used to abut and limit the long strip 30, preventing the connector 40 from moving downward and disengaging from the long strip 30, thus improving the stability of the rotatable connection between the connector 40 and the long strip 30. Furthermore, multiple locking slots 41 are provided, allowing one of the locking slots 41 to be quickly aligned with the locking block 50, improving work efficiency.

[0053] Furthermore, each extension arm 42 has an arc-shaped transition portion 421 at its extended end, which has a smooth surface to prevent scratches to workers when rotating the connecting piece 40.

[0054] Furthermore, it can be used in conjunction with the elastic element 60, the slider 70, and the hinge rod 71. Because the surface of the arc-shaped transition portion 421 is smooth, there is no need for manual alignment of the locking groove 41 and the locking block 50. Simply have the robotic arm surround the outer periphery of the upright 20 between the sliding sleeve 90 and the limiting sleeve 91, and slide downwards to push the sliding sleeve 90. The sliding bar 92 drives the limiting sleeve 91 downwards, causing it to leave the limiting card 11 and release the restriction on the hanging platform 21. The sliding sleeve 90 pushes the slider 70 downwards and compresses the elastic element 60. The slider 70, through the hinge rod 71, pushes the locking block 50 closer to the connecting member 40. The locking block 50 can directly enter a locking groove 41, or it can be pushed to the outer end of the extension arm 42 and, guided by the arc-shaped transition portion 421, enter the locking groove 41. This avoids the tedious process of manually aligning a locking groove 41 with the locking block 50, improving work efficiency.

[0055] In some embodiments, the opening width of the locking groove 41 gradually increases, and the locking block 50 is provided with a retractable part 51 on the side near the connector 40 that can be engaged in the locking groove 41.

[0056] Specifically, the retractable part 51 has a pointed tip facing the connector 40, which facilitates the insertion of the retractable part 51 into the locking groove 41. At the same time, the shape of the locking groove 41 matches the shape of the retractable part 51, so that the retractable part 51 can be stably placed in the locking groove 41 and abut against the inner wall of the locking groove 41.

[0057] Furthermore, it can be used in conjunction with the elastic element 60, the slider 70, and the hinge rod 71. The two side walls of the retractable part 51 are inclined, and the two opposite side walls of the locking groove 41 are also inclined. If the locking block 50 is pushed to the outer end of the extension arm 42 and enters the locking groove 41 under the guidance of the arc-shaped transition part 421, and under the mutual guidance of the inclined surfaces on the locking block 50 and the locking groove 41, the retractable part 51 is stably embedded in the locking groove 41, ensuring the limiting effect on the connecting member 40, avoiding the tedious process of manually aligning a locking groove 41 with the locking block 50, and improving work efficiency.

[0058] Optionally, locking slots 41 are provided at intervals in the circumferential direction of the connector 40.

[0059] In one possible implementation, the aforementioned connector 40 adopts, as shown in... Figure 1 The structure shown is described in the following document. Figure 1 The connector 40 is threaded with a locking nut 43 located below the long plate 30, and the top surface of the locking nut 43 can abut against the bottom wall of the long plate 30.

[0060] Specifically, the locking nut 43 can rotate upwards and press against the bottom of the long strip 30, thereby locking the connector 40 and preventing the connector 40 from rotating.

[0061] After the wax tree thread is connected to the connector 40, the worker can hold the fixed connector 40 with one hand and rotate the locking nut 43 with the other hand to press it upward against the bottom of the long strip 30, thereby locking the connector 40. Based on the limiting of the locking block 50 and the locking groove 41, the rotation of the connector 40 is further restricted.

[0062] In one possible implementation, the aforementioned pole 20 adopts the following... Figure 1 The structure shown is described in the following document. Figure 1 The lower end of the upright 20 is provided with an installation plate 80 extending horizontally, and a long strip 30 is connected to the upper surface of the installation plate 80.

[0063] Specifically, the mounting plate 80 is used to install the long strip plate 30. The long strip plate 30 is welded to the upper end surface of the mounting plate 80 and extends radially along the upright 20. The installation of the mounting plate 80 facilitates the installation of multiple long strip plates 30, which in turn facilitates the simultaneous application of slurry and sand to multiple wax trees.

[0064] Optionally, several uprights 20 are spaced apart on the support frame 10, allowing multiple uprights 20 to be hung from the support frame 10, so that the robot can grasp multiple uprights 20 one by one, thus improving work efficiency.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
