Description

Technical Field

[0001] This application relates to the field of machinery, and more specifically, to a microporous surface treatment device for cast aluminum alloy ingots. Background Technology

[0002] In the production and processing of cast aluminum alloy ingots, micropores are often generated on their surface due to casting process defects. These micropores not only affect the appearance quality of the ingot, but may also reduce the mechanical properties and corrosion resistance of the material. Therefore, it is necessary to repair or grind the micropores through a special surface treatment process.

[0003] Currently, surface treatment of micropores in aluminum alloy ingots largely relies on manual operation or traditional polishing equipment. However, this approach presents several technical challenges in practical applications: First, insufficient positioning accuracy. Traditional equipment often employs manual clamping or single-specification fixtures, making it difficult to adapt to aluminum alloy ingots of different sizes. Furthermore, ingot misalignment during clamping can lead to uneven micropore treatment during subsequent polishing, with some areas being over-polished while others retain micropores, thus affecting the overall quality. Second, inconvenient polishing adjustments. Existing equipment often uses a crude, manual control method for adjusting the polishing components, making it difficult to precisely control the contact pressure and depth between the polishing disc and the ingot surface. This hinders flexible adjustments to the treatment intensity based on parameters such as micropore size and distribution density, potentially resulting in incomplete micropore treatment or excessive wear on the ingot surface. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a microporous surface treatment device for cast aluminum alloy ingots to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A microporous surface treatment device for cast aluminum alloy ingots includes a base and a bent frame welded to one end of the base surface. The device is characterized in that: a positioning component is embedded at the other end of the base surface, the inner end of the clamping end of the positioning component corresponds horizontally to the base surface; a frame component is welded to the outer end of the bent frame; a vertical moving component is installed inside the frame component; a polishing component is provided at the bottom end of the vertical moving component, and the polishing end of the polishing component corresponds to the clamping end of the positioning component.

[0007] Furthermore, the positioning assembly includes a mounting groove, a dovetail groove, two dovetail blocks, a bearing, a double-ended ball screw, two ball nuts, a drive motor, and two positioning fixtures. The mounting groove is formed at the other end of the base surface, and the dovetail groove is formed inside the mounting groove. One end of the dovetail groove has a through hole, and the other end is fitted with the bearing. The two dovetail blocks are slidably mounted at both ends inside the dovetail groove, and two ball nuts are fixedly installed inside each block. One end of the double-ended ball screw is fixedly connected to the inner ring of the bearing, and its outer wall is connected to the inner ring balls of the two ball nuts. The drive motor is bolted to the outer wall of the base, and its output end is fixedly connected to the other end of the double-ended ball screw through the through hole at one end of the dovetail groove. The bottom ends of the two positioning fixtures are respectively attached to both ends of the inner wall of the mounting groove and are bolted to the surfaces of the two dovetail blocks.

[0008] Furthermore, the clamping end of the positioning fixture has a stepped shape, and the lowest surface of the stepped shape corresponds horizontally to the surface of the base.

[0009] Furthermore, the frame assembly includes a protective shell and a fixing cover. The outer wall of the protective shell is welded to the outer end of the top of the curved frame, and the vertical moving assembly is installed inside it. The fixing cover is fixedly connected to the outer end of the protective shell by bolts.

[0010] Furthermore, the vertical movement assembly includes an adjusting column, a gear, an annular groove, a limiting knob, a rack, a pressure rod, and two supporting bolts. The gear is integrally formed on the outer wall of the adjusting column, and the annular groove is opened at one end, while the pressure rod is sleeved at the other end. The annular groove end of the adjusting column is inserted into the side wall of the protective shell. The limiting knob is threadedly connected to the first threaded hole on the top of the outer side of the protective shell and fits against the inside of the annular groove. The rack is placed between the protective shell and the fixing cover, and the tooth ends mesh with the gear. The outer walls of the two supporting bolts are respectively threaded into the second threaded holes on the outer wall of the fixing cover, and their bottom ends abut against the outer wall of the rack.

[0011] Furthermore, the polishing assembly includes a drive, a protective cover, a polishing motor, and a polishing disc. The drive is installed at the top inside the protective cover, and the polishing disc is installed at the bottom. The top of the protective cover is welded to the bottom of the rack, and the bottom protects the surface of the polishing disc. The polishing motor is fixedly installed on the outer wall of the protective cover, and its output end is securely connected to the drive.

[0012] This utility model has the following beneficial effects:

[0013] 1. The positioning component of this utility model is highly practical. A drive motor rotates a double-headed ball screw, and with the cooperation of two ball nuts and a dovetail block, two positioning clamps can move precisely and synchronously in opposite directions within the dovetail groove, achieving rapid clamping and positioning of aluminum alloy ingots of different sizes, significantly improving positioning efficiency. The stepped shape of the clamping end of the positioning clamp can adapt to various ingot specifications, and its lowest surface corresponds horizontally to the base surface, ensuring the flatness of the ingot surface after clamping. This provides a stable and reliable benchmark for subsequent polishing, effectively solving the problem of uneven polishing caused by inaccurate positioning.

[0014] 2. This utility model's vertical moving component makes polishing operations more convenient and precise. By rotating the adjusting column, the polishing component can be easily moved vertically through the meshing transmission of gears and racks. The cooperation between the limiting knob and the annular groove effectively limits the adjusting column, preventing displacement during operation; the two supporting bolts tighten and fix the rack, ensuring stable operation of the polishing component at the set height. This adjustment method is not only simple to operate, but also allows for precise control of the contact pressure and distance between the polishing disc and the aluminum alloy ingot surface, facilitating the adjustment of the polishing depth according to the actual conditions of the micropores, making the micropore surface treatment effect more in line with process requirements.

[0015] 3. The gear and rack meshing transmission combined with the axial locking of the ring groove and the limiting knob in this utility model realizes stepless adjustment of the vertical displacement of the polishing component. At the same time, the supporting bolt tightens the outer wall of the rack, eliminates the gear meshing gap, and ensures that the polishing depth does not drift. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in 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.

[0023] Example:

[0024] Please see Figure 1 , Figure 2 , Figure 4 A microporous surface treatment device for cast aluminum alloy ingots includes a base 1 and a bent frame 2 welded to one end of the surface of the base 1.

[0025] The base 1, serving as the foundation platform, is made of steel plate with a finely polished surface, ensuring a flatness error of no more than 0.1mm to guarantee the stability and accuracy of other component installations. Each of the four corners of the base 1 has a 15mm diameter mounting hole for securing the entire device to the workbench.

[0026] The bending frame 2 is made of round steel and has an arc shape. One end of the bending frame 2 is welded to the middle of one end of the surface of the base 1. The weld is firm and the weld strength is not less than 80% of the strength of the base material. The other end of the bending frame 2 is welded to the protective shell 41 of the frame assembly 4, which provides sufficient support height and space.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A microporous surface treatment device for cast aluminum alloy ingots includes a base 1 with a positioning component 3 embedded at the other end of the base 1. The inner end of the clamping end of the positioning component 3 corresponds horizontally to the surface of the base 1. A frame component 4 is welded to the outer end of the bent frame 2. A vertical moving component 5 is installed inside the frame component 4. A polishing component 6 is provided at the bottom of the vertical moving component 5. The polishing end of the polishing component 6 corresponds to the clamping end of the positioning component 3. The positioning component 3 includes a mounting groove 31, a dovetail groove 32, two dovetail blocks 33, a bearing 34, a double-ended ball screw 35, two ball nuts 36, a drive motor 37, and two positioning clamps 38. The frame component 4 includes a protective shell 41 and a fixing cover 42. The vertical moving component 5 includes an adjusting column 51, a gear 52, an annular groove 53, a limit knob 54, a rack 55, a pressure rod 56, and two top holding bolts 57. The polishing component 6 includes a transmission device 61, a protective cover 62, a polishing motor 63, and a polishing disc 64.

[0028] The positioning assembly 3 mainly consists of a mounting groove 31, a dovetail groove 32, two dovetail blocks 33, a bearing 34, a double-ended ball screw 35, two ball nuts 36, a drive motor 37, and two positioning clamps 38. The mounting groove 31 is located at the other end of the surface of the base 1, providing installation space for the entire positioning assembly 3; the inner wall of the mounting groove 31 is flat and smooth, providing a good foundation for the stable installation and movement of the positioning clamps 38. The dovetail groove 32 is set inside the mounting groove 31, serving to guide and restrict the movement direction of the dovetail block 33. The two dovetail blocks 33 are slidably installed at both ends inside the dovetail groove 32, and can make linear reciprocating motion along the dovetail groove 32. The shape of the dovetail block 33 matches the dovetail groove 32, ensuring that the dovetail block 33 will not loosen during the movement. The bearing 34 is embedded in one end inside the dovetail groove 32, and its inner ring is fixedly connected to one end of the double-ended ball screw 35. The installation of the bearing 34 ensures that the double-ended ball screw 35 can rotate stably, reducing friction and vibration during the rotation process, and improving the transmission accuracy and stability of the positioning component 3. The double-ended ball screw 35, in conjunction with two ball nuts 36, converts the linear motion provided by the drive motor 37 into linear motion. This linear motion, along with the two dovetail blocks 33 fixedly connected to the two ball nuts 36, causes the two positioning clamps 38 to move closer or further apart. The drive motor 37 is bolted to the base 1, and its output end is fixedly connected to the end of the double-ended ball screw 35 in the through hole via a clamping method or coupling. This ensures that the drive motor 37 provides stable power for the rotation of the double-ended ball screw 35. The drive motor 37 has advantages such as adjustable speed, high control precision, and fast response speed, enabling precise control of the rotational speed and direction of the double-ended ball screw 35 according to actual needs, thereby achieving precise control of the position of the positioning clamps 38. The two positioning clamps 38 are bolted to the two dovetail blocks 33 respectively, and are used to clamp and position the cast aluminum alloy ingot. The bolt head of the fixed positioning fixture 38 is lower than the stepped surface of the clamping end of the positioning fixture 38; the lowest surface of the stepped shape corresponds horizontally to the surface of the base 1, which can prevent the aluminum alloy ingot from sliding during the positioning process, and also play a buffering role to avoid damage to the surface of the aluminum alloy ingot.

[0029] in,

[0030] When the positioning component 3 is not activated, the two positioning clamps 38 are at their extreme positions at both ends of the dovetail groove 32, with the maximum distance between them, to facilitate the placement of the cast aluminum alloy ingot. Placing the aluminum alloy ingot: The cast aluminum alloy ingot to be processed is placed in the mounting groove 31, positioned between the two positioning clamps 38, and the position of the aluminum alloy ingot is adjusted to be approximately centered. Starting the drive motor 37: Press the control button to start the drive motor 37. The drive motor 37 drives the double-ended ball screw 35 to rotate. Due to the cooperation between the double-ended ball screw 35 and the two ball nuts 36, the two ball nuts 36 respectively drive the two dovetail blocks 33 to move linearly towards the center along the dovetail groove 32. Clamping the aluminum alloy ingot: As the dovetail blocks 33 move, the two positioning clamps 38 gradually approach until they are in close contact with the two side surfaces of the cast aluminum alloy ingot, clamping and fixing the aluminum alloy ingot in the predetermined position within the mounting groove 31. At this time, the drive motor 37 stops rotating and maintains the positioning state through a braking device. After processing, release: Once the microporous surface treatment of the cast aluminum alloy ingot is complete, restart the drive motor 37 to rotate in the opposite direction. The double-ended ball screw 35 also rotates in the opposite direction, driving the two dovetail blocks 33 and the positioning clamp 38 to move towards both ends, releasing the clamp on the aluminum alloy ingot. Remove the processed aluminum alloy ingot, completing one positioning operation.

[0031] The frame assembly 4 mainly consists of two parts: a protective shell 41 and a fixing cover 42. The protective shell 41, as the main structure of the frame, has its outer wall welded to the top outer end of the bending frame 2, providing solid support and protective space for the vertically moving assembly 5 installed inside. The fixing cover 42 is fixedly connected to the outer end of the protective shell 41 by bolts, which serves to close the protective shell 41, further enhancing the protection of the internal components, while also facilitating the installation, debugging and maintenance of the internal components.

[0032] To prevent dust, moisture, and other impurities from entering the interior of the protective housing 41 and affecting the normal operation of the vertical moving component 5, a sealing gasket is provided between the contact surface of the fixed cover 42 and the protective housing 41. When installing the fixed cover 42, the sealing gasket is placed flat on the contact surface at the outer end of the protective housing 41, and then the fixed cover 42 is installed and the bolts are tightened, so that the sealing gasket is uniformly compressed, thereby achieving a good sealing effect.

[0033] The vertical movement assembly 5 mainly consists of an adjusting column 51, a gear 52, an annular groove 53, a limiting knob 54, a rack 55, a pressure rod 56, and two supporting bolts 57. The adjusting column 51, as the core component, has a gear 52 integrally formed on its outer wall. One end has an annular groove 53 for connection and limiting with the protective shell 41, and the other end is fitted with the pressure rod 56 for operation. The gear 52 meshes with the rack 55, converting the rotational motion of the adjusting column 51 into the vertical linear motion of the rack 55. The limiting knob 54, through a threaded connection with the protective shell 41 and fitting into the annular groove 53, achieves axial limiting of the adjusting column 51. The two supporting bolts 57 are used to fix the position of the rack 55, ensuring the stability of vertical movement. All components cooperate to realize the function of the vertical movement assembly 5. When vertical movement is required, the operator rotates the pressure rod 56 to drive the adjusting column 51 to rotate. Because the gear 52, integrally formed on the outer wall of the adjusting column 51, meshes with the rack 55, the rotational motion of the adjusting column 51 is converted into the vertical linear motion of the rack 55. The limit knob 54, through its threaded connection to the protective shell 41 and engagement with the annular groove 53 of the adjusting column 51, restricts the axial movement of the adjusting column 51, ensuring that the gear 52 and rack 55 always maintain a good meshing state. Two support bolts 57 are used to fix the position of the rack 55. When it is necessary to move the rack 55, use a wrench to loosen the two support bolts 57 appropriately, creating a certain gap between the bottom end of the support bolts 57 and the outer wall of the rack 55. At this time, the rack 55 can move freely in the vertical direction. Meshing adjustment: Manually rotate the adjusting column 51 and observe the meshing of the gear 52 and rack 55. If problems such as uneven meshing, jamming, or excessive noise are found, adjust the position of the adjusting column 51 or the installation angle of the rack 55 to ensure uniform meshing clearance and smooth transmission between the gear 52 and rack 55. Vertical movement accuracy adjustment: Using measuring tools such as a dial indicator, select multiple measuring points on rack 55 to measure the displacement accuracy of rack 55 during vertical movement. If the accuracy does not meet the requirements, check the machining accuracy of the guide groove and the installation straightness of rack 55, and adjust and repair any problems to ensure that rack 55 can move accurately in the vertical direction. Top bolt adjustment: Tighten and loosen the top bolt 57 when rack 55 moves to different positions to check the fixing effect and movement flexibility of rack 55. Adjust the tightening torque of the top bolt 57 so that rack 55 can be firmly fixed when needed, and can move easily after loosening the top bolt 57.

[0034] The polishing assembly 6 mainly consists of a transmission device 61, a protective cover 62, a polishing motor 63, and polishing discs 64. The transmission device 61, as the core component for power transmission and conversion, is installed at the top inside the protective cover 62, transmitting the rotational power of the polishing motor 63 to the polishing discs 64. The transmission device 61 employs a multi-stage gear transmission structure, including one driving gear and three driven gears. The driving gear is securely connected to the output end of the polishing motor 63, and the driven gears mesh sequentially, ultimately transmitting power to the polishing discs 64. The protective cover 62 not only protects the surfaces of the internal transmission device 61 and the polishing discs 64 but also is welded to the bottom of the rack 55, fixing the polishing assembly 6 at the bottom of the vertical moving assembly 5. The polishing motor 63 is fixedly installed on the outer wall of the protective cover 62, providing power for the entire polishing process. The polishing discs 64 are installed at the bottom of the transmission device 61, directly contacting the surface of the aluminum alloy ingot for polishing. All components cooperate to complete the polishing treatment of the microporous surface of the cast aluminum alloy ingot.

[0035] It should be noted that the specific models and specifications of bearing 34, double-ended ball screw 35, ball nut 36, drive motor 37, gear 52, rack 55, transmission 55, polishing motor 63, and polishing disc 64 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and operating principle of the drive motor 37 and the polishing motor 63 are clear to those skilled in the art and will not be described in detail here.

[0037] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
