Description

Technical Field

[0001] This utility model belongs to the technical field of casting processing equipment, and in particular relates to an electrically controlled actuator casting cutting device. Background Technology

[0002] As a key component of automated control systems, the housing of electronic actuators is generally made by casting. However, in subsequent finishing processes, excess parts such as risers, parting lines, and flash must be precisely cut to ensure the final assembly accuracy and appearance quality of the actuator. However, existing cutting devices have significant drawbacks in practical applications: they mostly use fixed-structure cutting machinery. When dealing with actuator castings with large cylinder diameters or complex structures, the limitations of the equipment's range of motion and tool path often prevent the continuous and complete machining of the entire annular area to be cut in a single setup.

[0003] Specifically, when processing aluminum alloy castings requiring circumferential cutting, such as typical DN200 actuator valve bodies or rotary actuator cylinder bodies, existing processes are limited by equipment capabilities. This often breaks down what should be a continuous circumferential cut into multiple discrete processing steps. Operators must first complete a cutting arc of approximately 120°, then interrupt the process, release the hydraulic clamps on the casting, and rely on manual experience to flip or rotate it at a specific angle before realigning and re-clamping it again before continuing with the next segment of cutting.

[0004] This "segmented, multi-step" operation method forces castings weighing tens of kilograms to be frequently turned over and repeatedly adjusted during processing. This not only severely disrupts the continuity of operations and leads to low production efficiency, but also makes it difficult to restore the initial theoretical benchmark during multiple clamping operations. This easily results in obvious quality defects such as steps, misalignment, or tilting at the cutting joints, which cannot meet the flatness requirements of high-end actuators for the sealing assembly surface. Ultimately, this directly affects the sealing performance, assembly accuracy, and service life of the product. Utility Model Content

[0005] This utility model provides an electric actuator casting cutting device to solve the problem that existing electric actuator cutting devices mostly use a fixed structure cutting machine to cut the actuator's cylinder and other components. However, because some actuators have large cylinder diameters, they cannot be fully cut after single-sided cutting, and the actuator needs to be flipped over and cut again. This frequent adjustment of the casting leads to low efficiency.

[0006] The present invention adopts the following technical solution: an electrically controlled actuator casting cutting device includes a support frame, a mounting plate fixedly connected to the top of the support frame, two mounting plates being provided in total, and the two mounting plates being fixedly arranged opposite to each other on the front and rear sides of the top surface of the support frame; a servo motor is fixedly connected to the front end face of the mounting plate located on the front side, an output shaft is provided on the rear side of the servo motor, and a drive gear is mounted on the output shaft; an annular groove is provided on the inner wall of the support frame, a guide ring frame is rotatably connected inside the annular groove, and an annular gear ring is fixedly connected in an annular array on the outer circumferential surface of the guide ring frame, the annular gear ring meshing with the drive gear for transmission; the servo motor and the drive gear together form a rotation drive structure for the guide ring frame inside the support frame.

[0007] Compared with the prior art, the present invention can achieve the following beneficial effects: In this invention, by setting up components such as a servo motor, a drive gear, a guide ring frame, and an annular gear ring, and through the transmission cooperation between the servo motor and the drive gear, as well as the meshing relationship between the drive gear and the outer annular gear ring of the guide ring frame, the guide ring frame can control its rotation within the annular groove on the inner wall of the support frame by the power output from the servo motor and the power transmitted by the drive gear. This, in turn, drives the laser cutting head on the guide ring frame to perform circumferential motion around the casting, achieving the effect of continuous cutting of the fixed electronic actuator casting through an annular cutting method. This eliminates the need for repeated flipping and adjustment of the casting, solving the problem of low cutting efficiency caused by frequent adjustments of the casting in existing devices.

[0008] By setting up components such as clamping push rod, clamping part, side support arm, and clamping seat, and through the fixed cooperation between the side support arm and the clamping seat, as well as the transmission cooperation between the clamping seat and the clamping push rod, and between the clamping push rod and the clamping part, the clamping part can control the clamping state of the casting through the extension and retraction power of the clamping push rod. This achieves stable positioning of the casting, fixes the casting of the electric actuator, avoids casting displacement during cutting, solves the problem of cutting accuracy being affected by unstable casting fixation or frequent adjustments in existing devices, and ensures the quality of casting cutting.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] Reference Figures 1 to 6 As shown, this utility model embodiment provides an electric actuator casting cutting device, including a support frame 1. The top of the support frame 1 is fixedly connected to a mounting plate 1012. There are two mounting plates 1012, and the two mounting plates 1012 are fixedly arranged opposite to each other on the front and rear sides of the top surface of the support frame 1.

[0015] A servo motor 1013 is fixedly connected to the front end face of the mounting plate 1012 located on the front side. An output shaft is provided on the rear side of the servo motor 1013, and a drive gear 1014 is mounted on the output shaft.

[0016] An annular groove is provided on the inner wall of the support frame 1. A guide ring frame 2 is rotatably connected inside the annular groove. An annular gear ring 201 is fixedly connected in an annular array on the outer circumference of the guide ring frame 2. The annular gear ring 201 meshes with the drive gear 1014 for transmission.

[0017] Based on the above technical concept, it can be understood that the servo motor 1013 drives the guide ring 2 to rotate in the annular groove of the support frame 1 through the meshing of the drive gear 1014 and the annular gear ring 201, so as to drive the laser cutting head 2015 mounted on the guide ring 2 to perform annular cutting around the fixed casting.

[0018] Furthermore, the servo motor 1013 and the drive gear 1014 together form a rotation drive structure for the guide ring frame 2 inside the support frame 1. Specifically, two mounting plates 1012 are fixed opposite each other on the front and rear sides of the top end of the support frame 1. The servo motor 1013 is fixed to the front end face of the front mounting plate 1012, and the drive gear 1014 is mounted on the output shaft of the servo motor 1013. Simultaneously, the annular gear ring 201 fixed in the annular array on the outer periphery of the guide ring frame 2, which is rotatably connected within the annular groove on the inner wall of the support frame 1, meshes with the drive gear 1014, thereby enabling the servo motor 1013 and the drive gear 1014 to drive the rotation of the guide ring frame 2 inside the support frame 1, providing power for adjusting the angle of the cutting component.

[0019] like Figure 2 As shown, in one embodiment of this utility model, a linear slide rail 2011 is fixedly connected to the inner wall of the guide ring frame 2. A longitudinal groove is formed inside the linear slide rail 2011, and a servo push rod 2012 is fixedly connected inside this longitudinal groove. The servo push rod 2012 is arranged longitudinally. It should be noted that through the cooperation of the linear slide rail 2011 and the servo push rod 2012, the laser cutting head 2015 is driven by the servo push rod 2012 to move longitudinally along the linear slide rail 2011, thereby achieving longitudinal feeding and positioning of the cutting head. Specifically, the linear slide rail 2011 is fixed to the inner wall of the guide ring frame 2, and the longitudinally arranged servo push rod 2012 is fixed inside the longitudinal groove of the linear slide rail 2011, so that the servo push rod 2012 can move stably along the longitudinal groove of the linear slide rail 2011.

[0020] like Figure 1As shown, in one embodiment of this utility model, a laser module 2013 is fixedly connected to the bottom end of the servo push rod 2012, and a guide slider 2014 is fixedly connected to the outside of the laser module 2013. There are two guide sliders 2014, which are fixedly arranged opposite to each other on the left and right sides of the laser module 2013. A laser cutting head 2015 is fixedly connected to the bottom end face of the laser module 2013. A linear slide rail 2011 is fixed on the inner wall of the guide ring frame 2, and a longitudinally arranged servo push rod 2012 is fixed in the longitudinal groove inside the linear slide rail 2011, so that the servo push rod 2012 can move stably along the longitudinal groove of the linear slide rail 2011.

[0021] like Figure 3 As shown, in one embodiment of this utility model, a lateral support arm 3 is fixedly connected to the outer wall of the support frame 1. The main body of the lateral support arm 3 is an L-shaped structure, and there are two lateral support arms 3. The two lateral support arms 3 are fixedly arranged opposite to each other on the left and right sides of the outer peripheral surface of the support frame 1. The purpose of the two L-shaped lateral support arms 3 being fixed opposite to each other on the left and right sides of the outer peripheral surface of the support frame 1 is to provide a stable support structure for the subsequent installation of the clamping part 3012, ensuring that the clamping part 3012 can be reliably installed and function.

[0022] like Figure 5 As shown, in one embodiment of this utility model, a clamping seat 301 is fixedly connected to the side of the two lateral support arms 3 that is away from the support frame 1. The main body of the clamping seat 301 is a ring structure, and a clamping push rod 3011 is fixedly connected to the inner side of the clamping seat 301. The ring structure clamping seat 301 is fixed on the side of the two lateral support arms 3 that is away from the support frame 1. It should be noted that fixing the clamping push rod 3011 on the inner side of the clamping seat 301 can provide a foundation for clamping the casting later.

[0023] like Figure 4 As shown, in one embodiment of this utility model, there are two clamping push rods 3011. The two clamping push rods 3011 are fixedly arranged opposite to each other on the left and right sides of the inner wall of the clamping seat 301. The inner side of each clamping push rod 3011 is fixedly connected to a clamping part 3012. The two clamping push rods 3011 are fixed opposite to each other on the left and right sides of the inner wall of the clamping seat 301. In specific implementation, the clamping part 3012 is fixed on the inner side of each clamping push rod 3011, so that the clamping push rod 3011 can push the clamping part 3012 to clamp the casting, realize the clamping and limiting of the casting, and prevent the casting from shifting during cutting.

[0024] Furthermore, such as Figure 3As shown, in one embodiment of this utility model, the clamping part 3012 has an arc-shaped structure. It can be understood that the clamping push rod 3011 and the clamping part 3012 together form a clamping and limiting structure for the casting. By setting the clamping part 3012 to an arc-shaped structure, in conjunction with the clamping push rod 3011 to form a clamping and limiting structure for the casting, the arc-shaped clamping part 3012 can better conform to the surface of the casting, improving the stability and reliability of clamping the casting.

[0025] like Figure 2 As shown, in one embodiment of this utility model, a support pad 101 is fixedly connected to the bottom surface of the support frame 1, and a fixing screw hole 1011 is provided inside the support pad 101. It can be understood that the proposed support pad 101 and the fixing screw hole 1011 together form a support structure for the support frame 1. The support pad 101 is fixed at the bottom of the support frame 1, and the fixing screw hole 1011 is provided inside the support pad 101. The support pad 101 supports the support frame 1, and the fixing screw hole 1011 makes it easy to fix the support pad 101 in a designated position, thereby ensuring the overall stability of the support frame 1.

[0026] Based on the above technical concept, in specific operation, the present invention uses the support pad 101 on the bottom surface of the support frame 1 to support and place the entire device. The support pad 101 can be fixed in the designated working position by using the fixing screw hole 1011 inside the support pad 101, thereby ensuring the stability of the support frame 1 and the entire device and providing a solid foundation for subsequent cutting operations. Next, the target electronic actuator casting to be cut is placed inside the clamping seats 301 at the ends of the two lateral support arms 3. The clamping push rods 3011 on the left and right sides of the inner wall of the clamping seat 301 are activated. The clamping push rods 3011 push the arc-shaped clamping part 3012 fixed on the inner side to move towards the casting until the two clamping parts 3012 are tightly attached to the surface of the casting. The clamping and limiting structure formed by the clamping push rods 3011 and the clamping parts 3012 achieves reliable clamping and fixing of the casting, preventing the casting from shifting during the cutting process. Subsequently, the servo push rod 2012 inside the linear slide rail 2011 on the inner wall of the guide ring frame 2 is activated. The servo push rod 2012 moves longitudinally along the longitudinal groove of the linear slide rail 2011, driving the laser module 2013 fixed at its bottom to move longitudinally in sync. The guide sliders 2014 on the left and right sides of the laser module 2013 slide along the inner wall of the longitudinal groove of the linear slide rail 2011, which guides and limits the movement of the laser module 2013, ensuring that the laser module 2013 moves stably until the laser cutting head 2015 at the bottom of the laser module 2013 is adjusted to the longitudinal height corresponding to the position of the casting to be cut. Finally, the servo motor 1013 fixed to the front end of the front mounting plate 1012 is started. The output shaft of the servo motor 1013 drives the drive gear 1014 mounted on it to rotate. Since the drive gear 1014 meshes with the annular gear ring 201 fixed in annular array on the outer circumference of the guide ring frame 2, when the drive gear 1014 rotates, it drives the guide ring frame 2 to rotate in annular groove in the inner wall of the support frame 1. During the rotation of the guide ring frame 2, it drives the linear slide rail 2011, servo push rod 2012, laser module 2013 and laser cutting head 2015 to perform circular motion synchronously. At the same time, the laser module 2013 is started and the laser cutting head 2015 emits laser to cut the casting. Through the continuous rotation of the guide ring frame 2, the annular continuous cutting of the casting is achieved, and the overall cutting operation can be completed without flipping.
