Abstract
Description
Technical Field
[0001] This application relates to the field of casting surface treatment technology, specifically to a casting surface treatment device for precision casting. Background Technology
[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then processing them by grinding and other subsequent means. This includes the casting of pipe fittings.
[0003] Currently, during the casting process of pipe fittings, if there is a slight bend on the surface of the pipe fitting, it will be corrected using a straightening device. After the correction, the next processing step is usually carried out directly. However, burrs are easily generated on the surface of the pipe fitting at the correction point. The presence of burrs will make the surface of the pipe fitting uneven, resulting in poor fit between the pipe fitting and other components during assembly, affecting the assembly accuracy and sealing performance. Utility Model Content
[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a surface treatment device for precision casting, so as to solve the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model provides a surface treatment device for precision casting, comprising a base frame, a support platform fixedly installed on the inner side of the base frame, a platform shaft fixedly passing through the inner side of the support platform, a support plate rotatably connected to the outer surface of the platform shaft, a cylinder fixedly installed on the top of the base frame, a shaping head fixedly connected to the output end of the cylinder, a tube fixing mechanism provided on the base frame, a fixed seat fixedly connected to one end of the base frame, and an adjustable grinding mechanism provided on the fixed seat.
[0006] Preferably, the pipe fixing mechanism includes a fixed frame fixedly connected to the inner side of the base frame, a rotating cylinder fixedly passing through the inner side of the fixed frame, and a rotating frame fixedly connected to one end of the rotating cylinder near the fixed frame. The pipe fixing mechanism enables the pipe and the rotating frame to be in the same motion state (i.e., the rotating frame and the pipe rotate synchronously or remain stationary).
[0007] Preferably, the bottom of the rotating frame is threaded with a screw, and the top of the screw is rotatably connected to a tube clamping plate.
[0008] Preferably, a motor is fixedly installed on the top of the base frame, a drive gear is fixedly connected to the output end of the motor, a chain is meshed with the outer surface of the drive gear, a transmission gear is fixedly sleeved on the outer surface of the rotating drum, and the outer surface of the transmission gear meshes with the inner end of the chain away from the drive gear.
[0009] Preferably, the adjustable grinding mechanism includes a lead screw rotatably connected to the inner wall of the fixed seat, a crank handle is provided at one end of the lead screw, and a shift plate is threaded on the outer surface of the lead screw. The number of shift plates is set to two sets. The adjustable grinding mechanism can adjust the two sets of grinding wheels to a suitable distance to adapt to the grinding of the corresponding pipe fittings.
[0010] Preferably, a slide is fixedly connected to the outer surface of the shifting plate, a motor is fixedly mounted on the slide, and a grinding wheel is fixedly connected to the output end of the motor.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This precision casting surface treatment device, through a cylinder and a straightening head, straightens the bent part of the pipe at the correct position on the support plate. Then, through the pipe fixing mechanism and the adjustable grinding mechanism, two sets of deburring treatment are carried out on the straightened part of the pipe, which effectively improves the flatness of the pipe surface. The flat surface reduces friction and wear during assembly and improves the fitting accuracy and sealing performance of the pipe with other components.
[0013] 2. After the surface treatment device for precision casting is completed, the device is cleverly designed to allow the pipe to be moved so that its correction part is moved between the two sets of grinding wheels. During this process, the pipe clamping plate clamps the pipe again to ensure its stability during the grinding process. By shaking the handle to drive the screw to rotate, the two sets of shifting plates move in opposite directions, thereby linking the two sets of sliding blocks to slide closer along the fixed seat until the grinding wheel contacts the pipe. This adjustable grinding operation can adapt to various types of pipes. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] Please see Figure 1-5 A surface treatment device for precision casting includes a base frame 1, a support platform 2 fixedly installed on the inner side of the base frame 1, a platform shaft 3 fixedly passing through the inner side of the support platform 2, a support plate 4 rotatably connected to the outer surface of the platform shaft 3, a cylinder 5 fixedly installed on the top of the base frame 1, a straightening head 6 fixedly connected to the output end of the cylinder 5, the teeth of the straightening head 6 being designed to better hold cylindrical tubes, the straightening head 6 being positioned above the two sets of support plates 4, a tube fixing mechanism being provided on the base frame 1, a fixing seat 16 being fixedly connected to one end of the base frame 1, and an adjustable grinding mechanism being provided on the fixing seat 16.
[0022] Through the above technical solution, in the process of calibrating the pipe fitting, the device first places the pipe fitting on two sets of support plates 4, with the part to be calibrated located directly below the calibrating head 6. The calibrating head 6 can be moved down by the cylinder 5, and the bending part can be corrected by the calibrating head 6. Then, the pipe fixing mechanism can be used in conjunction with the adjustable grinding mechanism to grind the calibrated part of the pipe fitting.
[0023] Specifically, the tube fixing mechanism includes a fixing frame 7 fixedly connected to the inner side of the base frame 1, a rotating cylinder 8 fixedly passing through the inner side of the fixing frame 7, and a rotating frame 9 fixedly connected to one end of the rotating cylinder 8 near the fixing frame 7.
[0024] Through the above technical solution, the rotating drum 8 and the rotating frame 9 rotate synchronously, and the pipe passes through the fixed frame 7, the rotating frame 9 and the rotating drum 8.
[0025] Specifically, the bottom of the rotating frame 9 is threadedly connected to a screw 10, and the top of the screw 10 is rotatably connected to a tube clamping plate 11.
[0026] Through the above technical solution, the rotating nail 10 can allow the pipe clamping plate 11 to gradually approach the pipe support during the rotation process, until the pipe clamping plate 11 is stably clamped on the pipe fitting, thus achieving a stable limiting effect.
[0027] Specifically, a motor 12 is fixedly installed on the top of the base frame 1, a drive gear 13 is fixedly connected to the output end of the motor 12, a chain 14 is meshed with the outer surface of the drive gear 13, a transmission gear 15 is fixedly sleeved on the outer surface of the rotating drum 8, and the outer surface of the transmission gear 15 is meshed with the inner side of the chain 14 away from the drive gear 13.
[0028] Through the above technical solution, the function of the drive gear 13, chain 14, and transmission gear 15 is to convert the rotation of the drive gear 13 driven by the motor 12 into the rotation of the drum 8.
[0029] Specifically, the adjustable grinding mechanism includes a lead screw 17 rotatably connected to the inner wall of the fixed base 16, a crank handle 18 is provided at one end of the lead screw 17, and a shift plate 19 is threaded on the outer surface of the lead screw 17, and two sets of shift plates 19 are provided.
[0030] Through the above technical solution, the outer surface of the lead screw 17 is provided with threads of the same length and opposite direction from the middle to both ends. This is so that during the rotation of the lead screw 17, the two sets of shift plates 19 can move in opposite directions along the lead screw 17 (closer or farther away from each other).
[0031] Specifically, a slide 20 is fixedly connected to the outer surface of the shift plate 19, a motor 21 is fixedly mounted on the slide 20, and a grinding wheel 22 is fixedly connected to the output end of the motor 21.
[0032] Through the above technical solution, the fixed base 16 has strip holes on both sides, and the shift plate 19 is slidably connected to the strip holes. This is to play a relative limiting role for the shift plate 19, so that the shift plate 19 can move along a fixed trajectory under the drive of the lead screw 17.
[0033] Working Principle: During the pipe fitting alignment process, the device first places the pipe fitting on two sets of support plates 4, with the part to be aligned directly below the alignment head 6. Then, the screw 10 is turned to move the clamping plate 11 upwards (i.e., the clamping plate 11 gradually approaches the pipe fitting, requiring manual fine-tuning of its position during this process), until the clamping plate 11 stably clamps the pipe fitting. After the pipe fitting is initially stabilized, the cylinder 5 drives the alignment head 6 downwards, allowing the downward pressure of the alignment head 6 to correct the bent portion of the pipe fitting. After correction, the pipe fitting needs to be moved, positioning the aligned portion between the two sets of grinding wheels 22 (during which the clamping plate 11 needs to be re-clamped onto the pipe fitting). Simultaneously, the distance between the two sets of grinding wheels 22 needs to be adjusted according to the pipe fitting's diameter. This is achieved by cranking the handle 18 to rotate the lead screw 17, which in turn drives... The two sets of shift plates 19 move in opposite directions, thereby linking the two sets of slide blocks 20 to slide closer along the fixed seat 16 until the two sets of grinding wheels 22 move to the position of contacting the pipe fitting. Then the motor 21 can be turned on to perform grinding operation on the pipe rack. At this time, the pipe fitting is in a relatively stable state under the holding action of the pipe clamping plate 11. In order to thoroughly deburr the bent parts, the motor 12 can be turned on to drive the drive gear 13 to rotate. With the transmission action of the chain 14, the transmission gear 15 can be linked to rotate, that is, the rotating drum 8 and the rotating frame 9 will be driven to rotate synchronously. The pipe fitting, which is in the same motion state as the rotating drum 8 and the rotating frame 9, will also be driven to rotate (the pipe fitting is stably held by the pipe clamping plate 11). During the rotation of the pipe fitting, the rotation of the grinding wheels 22 can effectively thoroughly deburr the bent correction parts, effectively improving the flatness of the pipe fitting surface.
[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
