Technical Field
[0001] This utility model relates to the field of alloy casting production technology, specifically to an alloy casting surface grinding machine. Background Technology
[0002] Alloy castings refer to parts or products with specific shapes and properties made from alloy materials (materials with metallic properties formed by the fusion of two or more metallic elements or metallic and non-metallic elements) through casting processes. After the casting is completed, the surface of the alloy casting needs to be ground to ensure the flatness of the surface. In the prior art, patent publication number CN202420326703.2 discloses a mold design and grinding platform, including a fixture with a shell fixedly installed on one side, a table board for protection fixedly installed on the top of the shell, a dust collection box for collection snapped onto one side of the shell, a dust extraction port for absorbing smoke and dust fixedly installed on one side of the shell, a safety lighting lamp fixedly installed on one side of the shell, and an electrically controlled door for control snapped onto one side of the shell. The above-mentioned mold design grinding platform has some problems in actual use. For example, the casting clamping plate structure uses a single threaded rod drive, and all the clamping plate support points converge at the support points of the threaded rod and the clamping plate. However, the casting inevitably vibrates during the grinding process, and long-term operation may lead to a deterioration in the clamping effect. The fan directly absorbs the airflow with debris, and there are a lot of debris in the airflow, which increases the load on the fan. Moreover, the subsequent debris collection and treatment is difficult. Therefore, we propose an alloy casting surface grinding machine. Utility Model Content

[0017] Please see Figure 1-7 This embodiment provides a technical solution: an alloy casting surface grinding machine, including a grinding table 1, grinding equipment 3, clamping mechanism 4 and filtering mechanism 9; Grinding table 1: It is equipped with a top mounting bracket 2 on its upper side and a controller 11 on the front side of the grinding table 1.

When the grinding machine is needed, the alloy casting can be placed on the primary placement platform 8. Then, the external air compressor pump can be adjusted to extend or retract the telescopic end of the second cylinder 7, thereby driving the primary placement platform 8 to adjust its height. Grinding device 3: It is located in the middle of the top mounting frame 2. Grinding device 3 includes a first cylinder 31, a grinding frame 32, a grinding column 33, and a grinding motor 34. The first cylinder 31 is located in the middle of the upper surface of the top mounting frame 2. The extension end of the first cylinder 31 is fixedly connected to the grinding frame 32. The grinding column 33 is rotatably connected between the front and rear inner walls of the grinding frame 32. The rear end of the grinding frame 32 is fixedly connected to the grinding motor 34. The output shaft of the grinding motor 34 is fixedly connected to the rear end of the grinding column 33. The input terminal is electrically connected to the output terminal of the controller 11. The air inlet of the first cylinder 31 is connected to an external air compressor pump. After that, the controller 11 can be controlled to operate the grinding motor 34. The output shaft of the grinding motor 34 rotates at high speed, which in turn drives the grinding column 33 to rotate at high speed. After that, the external air compressor pump can be controlled to operate the first cylinder 31. The extension and retraction end of the first cylinder 31 extends or retracts, which in turn drives the grinding frame 32 to adjust its height, which in turn drives the high-speed rotating grinding column 33 to adjust its height. Clamping mechanism 4 includes a limiting rod 41, a slide table 42, a slide groove 43, a slide seat 44, a push rod 45, a fixed seat 46, a movable clamping plate 47, and a telescopic rod 48. The limiting rods 41 are symmetrically fixed between the front and rear inner walls of the grinding table 1. The outer arc surfaces of the two limiting rods 41 are slidably connected to the slide table 42. The front side wall of the front slide table 42 is symmetrically provided with slide grooves 43. The interior of the two slide grooves 43 is slidably connected to the slide seats 44. The interior of the two slide seats 44 is rotatably connected to the push rods 45. The rear ends of the two push rods 45 are rotatably connected to the fixed seats 46. The rear sides of the two fixed seats 46 are fixedly connected to the slide table 47. A movable clamping plate 47 is connected to the front side of the movable clamping plate 47 and the front side wall of the front slide table 42. A telescopic rod 48 is fixedly connected between the front side of the movable clamping plate 47 and the front side wall of the front slide table 42. The clamping mechanism 4 also includes a torsion valve 49. Screws are rotatably connected inside the two slide grooves 43. The two screws are fixedly connected to each other and threaded to the middle of the slide seat 44 located in the same slide groove 43. The threads of the two screws are opposite in direction. The right end of the right screw is fixedly connected to the torsion valve 49. Bellows are fixedly connected to the left and right sides of the two slide seats 44, respectively. The ends of the bellows are fixedly connected to the side walls of the corresponding slide grooves 43. The bellows hold the screws... The exposed threaded portion is sealed. As the slide 44 moves left and right, the bellows will adaptively expand and contract to prevent dirt from contaminating the outer thread surface. A fixing clamp 5 is fixedly connected to the rear side of the upper surface of the rear slide 42. A third cylinder 10 is provided on the left side of the grinding table 1. The telescopic end of the third cylinder 10 is fixedly connected to the left side of the left side of the left side baffle 6. The air inlet of the third cylinder 10 is connected to an external air compressor pump, which forces the upper surface of the primary placement table 8 to be at the same level as the lower side wall of the slide 42. At this time, the torsion valve 49 can be manually turned, thereby driving the two screws to rotate, and the threads of the two screws... Since the directions are opposite, the two slides 44 will move relatively far apart or relatively close together, and then push the moving clamp 47 to move backward through the push rod 45 until the rear side of the moving clamp 47 clamps the front and rear sides of the alloy casting with the front side of the fixed clamp 5. At this time, the external air compressor pump is adjusted, and the extension end of the second cylinder 7 extends or retracts, driving the two second cylinders 7 to move left and right, thereby driving the clamped alloy casting to move left and right. At this time, the left and right movement of the alloy casting can be controlled, and the high-speed rotating grinding column 33 moves up and down to grind the upper surface of the clamped alloy casting. Filtering mechanism 9: Located on the underside of the grinding table 1, the filtering mechanism 9 includes an exhaust hopper 91, slots 92, lugs 93, a bucket frame 94, a filter screen 95, and a handle 96. The exhaust hoppers 91 are evenly distributed on the upper surface of the grinding table 1. Slots 92 are provided at the four corners of the upper surface of the exhaust hopper 91. Lugs 93 are placed inside the slots 92. A bucket frame 94 is fixedly connected to the underside of every four lugs 93 located in the same exhaust hopper 91. A filter screen 95 is provided on the lower side of the inside of each bucket frame 94. A handle 96 is fixedly connected to the upper side of each bucket frame 94. A baffle 6 is fixedly connected to the left side of each of the two slides 42, and a baffle 6 is also fixedly connected to the right side of each of the two slides 42. Every three vertical... The adjacent exhaust hopper 91 is connected to an external exhaust fan via a ventilation duct. During the grinding process, a large amount of iron filings are generated. The flying iron filings will bounce onto the surface of the baffle plate 6 and then fall into the exhaust hopper 91. At this time, the external exhaust fan can be adjusted to generate a negative pressure airflow on the upper side of the exhaust hopper 91. The negative pressure airflow enters the interior of the ventilation duct along the exhaust hopper 91 and is drawn out by the external exhaust fan. During this period, the negative pressure airflow carries the iron filings, which are blocked by the filter screen 95 and remain inside the bucket frame 94. When there are too many iron filings in the bucket frame 94, the handle 96 can be manually lifted to pull out the bucket frame 94 and remove the iron filings that fall into it. Then the bucket frame 94 can be put back into the exhaust hopper 91.
[0018] The working principle of the alloy casting surface grinding machine provided by this utility model is as follows: When the grinding machine is needed, the alloy casting can be placed on the primary placement platform 8. Then, the external air compressor pump can be adjusted to extend or retract the telescopic end of the second cylinder 7, thereby driving the primary placement platform 8 to adjust its height, forcing the upper surface of the primary placement platform 8 to be at the same level as the lower side wall of the slide table 42. At this time, the torsion valve 49 can be manually turned, thereby driving the two screws to rotate. The threads of the two screws are opposite, so the two slides 44 will move relatively far apart or relatively close together. Then, the push rod 45 pushes the moving clamp 47 to move backward until the rear side of the moving clamp 47 clamps the front and rear sides of the alloy casting with the front side of the fixed clamp 5. After that, the controller 11 can be adjusted to operate the grinding motor 34. The output shaft of the grinding motor 34 rotates at high speed, thereby driving the grinding column 33 to rotate at high speed. After that, the external air compressor pump can be adjusted to operate the first cylinder 31. The telescopic end of the first cylinder 31 extends or retracts, thereby... The height of the grinding frame 32 is adjusted, which in turn adjusts the height of the high-speed rotating grinding column 33. At this time, the external air compressor pump is controlled, causing the extension or retraction of the second cylinder 7, which in turn moves the two second cylinders 7 left and right, thus moving the clamped alloy casting left and right. This allows control of the alloy casting's left and right movement, while the high-speed rotating grinding column 33 moves up and down, grinding the upper surface of the clamped alloy casting. During grinding, a large amount of iron filings are generated, and the flying iron filings will bounce onto the surface of the baffle plate 6. The iron filings fall into the exhaust hopper 91. At this time, the external exhaust fan can be adjusted to generate a negative pressure airflow on the upper side of the exhaust hopper 91. The negative pressure airflow enters the ventilation pipe along the exhaust hopper 91 and is drawn out by the external exhaust fan. During this process, the negative pressure airflow carries iron filings, which are blocked by the filter screen 95 and remain inside the bucket frame 94. When there are more iron filings in the bucket frame 94, the handle 96 can be manually lifted to pull out the bucket frame 94 and release the iron filings inside. Then the bucket frame 94 can be put back into the exhaust hopper 91.
[0019] It is worth noting that the core chip of the controller 11 disclosed in the above embodiments is a single-chip microcomputer, specifically the S7-200. The first cylinder 31, the grinding motor 34, the second cylinder 7, and the third cylinder 10 can be freely configured according to the actual application scenario. It is recommended that the first cylinder 31 and the second cylinder 7 be QGB series standard cylinders, the third cylinder 10 be AS series standard cylinders, and the grinding motor 34 be a 57BL55S02-212 brushless motor. The controller 11 controls the operation of the grinding motor 34 using methods commonly used in the prior art.
