Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, and specifically to a grinding device for casting processing. Background Art

[0002] A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, through subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. After the casting is completed, it needs to be ground to remove burrs and protrusions and improve the surface roughness.

[0003] At present, there are various grinding devices for casting processing. Generally, an artificial hand-held angle grinder is used. This grinding method is relatively traditional and the processing accuracy is not high; when using automated equipment, the casting is mainly fixed, and a grinding wheel driven by a robotic arm rotates at high speed and approaches the casting to achieve grinding, including grinding of plates, pipes and inclined surfaces, etc. However, in common automated equipment, the grinding method has certain defects.

[0004] First, for grinding of an inclined surface, the relative position between the casting and the fixture needs to be adjusted, so that the casting corresponds to the grinding wheel, resulting in a more cumbersome fixation of the casting; second, when grinding the cutting end of a plate, the bottom end of the grinding wheel is often used for grinding. This grinding method makes the grinding lines arc-shaped and the processing accuracy is relatively low; third, for grinding the end of a pipe fitting, an independently designed grinding device is often used, and the edge of the end of the pipe fitting is not ground with high precision, reducing the grinding quality; fourth, after some grinding devices complete grinding, most of the casting waste chips splash on the operating table and the ground, and subsequent cleaning is required. Therefore, we provide a grinding device for casting processing to solve the above problems. Summary of the Invention

Detailed implementation manners

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0032] The present invention provides a grinding device for casting processing, which includes a base 1. On one side of the top of the base 1, two corresponding mounting plates 2 are fixedly arranged. A grinding mechanism 3 is arranged between the two mounting plates 2.

The cylinder 33 can drive the grinding wheel 36 to approach the casting on the top of the base 1, and the self-locking motor can drive the cylinder 33 and the grinding wheel 36 to swing, so that the grinding wheel 36 can grind the inclined surface of the casting. A driving group 37 is arranged on the rotating shaft 35 to start the rotation of the grinding wheel 36. It should be noted that the grinding wheel 36 can be replaced with different sizes according to the casting, and an arc-shaped groove is opened at the bottom edge of the axial surface of the grinding wheel 36, and this arc-shaped groove can chamfer the grinding edge of the casting.

[0033] A cleaning mechanism 4 is arranged on one of the mounting plates 2. The cleaning mechanism 4 includes a blower 41. The blower 41 is installed on the outer wall of the corresponding mounting plate 2. The input end of the blower 41 penetrates through the inside of the corresponding mounting plate 2 and is fixedly connected with a telescopic tube 42. One end of the telescopic tube 42 is provided with a connecting tube 43. The blower 41 serves as a power source to collect the waste chips generated by grinding. The connecting tube 43 and the telescopic tube 42 are fixedly connected through a fastening sleeve 44. When the grinding wheel 36 moves horizontally, due to the telescopic characteristic of the telescopic tube 42, the connecting tube 43 can always maintain a gas-collecting state. The fastening sleeve 44 is bolted to one end of the connecting plate 34. The input end of the connecting tube 43 is fixedly communicated with a gas-collecting ring 45. The gas-collecting ring 45 is sleeved on the outer side of the top of the grinding wheel 36. A plurality of air holes are arranged in an annular array on the inner side of the bottom of the gas-collecting ring 45. This design increases the area for collecting waste chips. The output end of the blower 41 is fixedly connected with a collection box 46. A filter screen 461 is fixedly arranged on one side wall of the collection box 46, and a door body 462 is arranged on the side of the collection box 46 away from the mounting plate 2. The operation of the blower 41 enables the waste chips to enter the collection box 46, and the gas is discharged through the filter screen 461, while the waste chips are retained in the collection box 46. When there is a large amount of waste chips retained, the door body 462 on one side of the collection box 46 can be opened to clean the waste chips.

[0034] Specifically, the sliding assembly 31 includes a driving motor 311. The driving motor 311 is installed on the outer side of one of the mounting plates 2. The output end of the driving motor 311 is fixedly connected to a screw rod 312. The screw rod 312 is rotatably arranged between the two mounting plates 2. A threaded sleeve 313 is threadedly connected to the outer wall of the screw rod 312. A slide rod 314 is arranged in parallel on one side of the screw rod 312. The slide rod 314 is fixedly arranged between the two mounting plates 2. A sliding sleeve 315 is slidably arranged on the outer wall of the slide rod 314. Two fixing plates 316 are fixedly arranged between the threaded sleeve 313 and the sliding sleeve 315. The self-locking motor 32 is installed on the outer side of one of the fixing plates 316. An installation sleeve 331 is fixedly arranged on the outer wall of the air cylinder 33. The installation sleeve 331 is rotatably arranged between the two fixing plates 316. The output end of the self-locking motor 32 is fixedly connected to one of the rotating shafts 35 of the installation sleeve 331. The driving motor can drive the screw rod 312 to rotate, and then drive the grinding wheel 36 to move horizontally through the threaded connection with the threaded sleeve 313, realizing the linear grinding of the casting by the grinding wheel 36. At the same time, since the self-locking motor 32 can be in a moving state, a through circular groove 21 is opened inside the corresponding mounting plate 2, so that the self-locking motor 32 can enter the inside of the circular groove 21, increasing the limit grinding distance of the grinding wheel 36 and reducing the overall floor area of the grinding device.

[0035] Specifically, the driving group 37 includes a driving motor 371. The driving motor 371 is installed on the top of the connecting plate 34, and the output shaft of the driving motor 371 is rotatably arranged inside the connecting plate 34. The output end of the driving motor 371 is fixedly connected to a driving gear 372. A driven gear 373 meshing with the driving gear 372 is fixedly sleeved on the outer wall of the rotating shaft 35. The driving motor 371 serves as a power source. Under the meshing of the driving gear 372 and the driven gear 373, the rotation of the grinding wheel 36 is driven. A protective shell 374 is sleeved outside the driving gear 372 and the driven gear 373. The protective shell 374 is fixedly installed at the bottom of the connecting plate 34. This design ensures the meshing stability of the driving gear 372 and the driven gear 373.

[0036] Specifically, a through convex slot is opened inside the grinding wheel 36. The bottom end of the rotating shaft 35 can be inserted into the inner cavity of the grinding wheel 36. The rotating shaft 35 is fixedly connected to the grinding wheel 36 through a fastening bolt 351. The fastening bolt 351 is configured as an internal hexagonal bolt. This design can facilitate the replacement of the grinding wheel 36, making the gear of the grinding wheel 36 fit the casting and improving the grinding efficiency.

[0037] Specifically, a fixing mechanism 5 is provided on the top of the base 1, and the fixing mechanism 5 includes a boss 51, which is a convex-shaped fixing platform for placing and fixing the casting, and an electric slide 52 is provided below the boss 51, and the electric slide 52 is installed at the bottom of the inner cavity of the base 1. A bottom plate 53 is fixedly provided on the sliding part of the electric slide 52, and a rod body 54 is fixedly provided on the top of the bottom plate 53. A rotating drum 55 is rotatably provided on the outer wall of the rod body 54, and a sliding member cooperating with the rotating drum 55 is provided on the top of the base 1. The groove 11 is rotated to extend to the outside of the slide groove 11 and is fixedly connected to the boss 51. The operation of the electric slide 52 can drive the boss 51 to approach the grinding wheel 36 to control the grinding depth. A self-locking motor 56 is installed on the top of the bottom plate 53. The output end of the self-locking motor 56 is fixedly connected to a bevel gear 57. The outer wall of the rotating drum 55 is fixedly sleeved with a bevel gear ring 58 meshing with the bevel gear 57. This design can adjust the grinding side of the casting after one fixation, thereby simplifying the fixing process of the casting.

[0038] Specifically, sliders 531 are integrally formed on both sides of the bottom of the base plate 53, and the inner cavity of the base 1 is fixedly provided with a slide rail 12 that cooperates with the slider 531. The slider 531 is slidably set in the inner cavity of the slide rail 12. Its design purpose is to ensure a certain stability of the boss 51 and improve the grinding accuracy of the casting.

[0039] Specifically, a plurality of electric push rods 511 in an annular array are fixedly installed at the bottom of the boss 51, and a clamping plate 512 is fixedly installed at the movable end of the electric push rod 511. A limiting groove 513 corresponding to the clamping plate 512 is opened on the outer side of the boss 51, and the clamping plate 512 is slidably arranged on the inner wall of the limiting groove 513. The electric push rods 511 are configured in four numbers and are respectively arranged on the four sides of the boss 51. This design can realize the centering and fixing of the casting. At the same time, when grinding one side of the casting, the electric push rod on that side can be started. The push rod 511 makes the corresponding clamping plate 512 away from the casting, and the remaining three electric push rods 511 can clamp the casting tightly, and the non-clamped side of the casting can be ground by the grinding wheel 36 without dead angles. A fixing cavity 514 is opened at the central position of the top of the boss 51. The cavity is used to fix the pipe fitting and can be fixed by bolts or pipe clamps. The clamping plate 512 is T-shaped. The T-shaped clamping plate 512 can increase the clamping area of ​​the casting and ensure the clamping stability of the casting.

[0040] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0041] Working principle: when it is necessary to grind a plate-shaped casting, a plurality of electric push rods 511 drive the clamping plate 512 to clamp and fix the casting, and the electric slide 52 is used to push the grinding surface of the casting to fit the axial surface of the grinding wheel 36, and then the electric push rod 511 corresponding to the grinding wheel 36 is started again to make the clamping plate 512 move away from the casting, and then the drive motor 2 371 is started to drive the grinding wheel 36 to rotate, and the grinding wheel 36 is driven to move downward and correspond to the casting by starting. At this time, the electric slide 52 is started again according to the grinding depth, and the drive motor 1 311 is started to drive the grinding wheel 36 to move horizontally, so as to achieve grinding of the casting without dead angles.

[0042] When the casting bevel needs to be processed, the self-locking motor 32 can be started according to the inclination angle of the bevel, so that the self-locking motor 32 drives the cylinder 33 and the grinding wheel 36 to swing, so that the axial surface of the grinding wheel 36 can fit with the grinding bevel, and the subsequent grinding principle is the same as that of grinding plate castings.

[0043] When it is necessary to grind the pipe fitting, a fixing fixture can be installed in the fixing cavity 514 or bolts can be used for centering and fixing. A grinding wheel 36 of appropriate size is selected according to the size of the pipe fitting, and the pipe fitting is driven to correspond to the grinding wheel 36 through the electric slide 52. The grinding wheel 36 is then driven to rotate through the drive group 37, and the bottom end of the grinding wheel 36 is used to grind the pipe fitting. At the same time, the bottom end of the grinding wheel 36 can be used to grind the key edges, thereby improving the grinding accuracy.

[0044] During the above grinding process of the casting, the fan 41 can be started to absorb the waste chips generated by grinding through the air collecting ring 45. The waste chips can enter the collection box 46, and the gas is discharged through the filter 461. The waste chips remain in the collection box 46. When a lot of waste chips remain, the door 462 on one side of the collection box 46 can be opened to clean the waste chips.
