Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, and particularly relates to a special-shaped blank polishing machine. BACKGROUND

[0002] The casting blank is a key step in the casting process, and the main purpose is to manufacture the metal parts with the required shape and size by melting the metal and cooling and solidifying in the mold. The casting blank is usually obtained by casting processing, and the shape can be irregular, geometric or designed and manufactured according to the required product.

[0003] The patent CN111496627B discloses an automobile flywheel blank surface polishing equipment, which comprises a rack, a fixed polishing mechanism, a movable polishing mechanism and a rotating clamping mechanism. The following problems existing in the polishing operation of the automobile flywheel casting blank can be solved: a. In the traditional polishing operation process, one polishing mechanism corresponds to one clamping mechanism. If different specifications of automobile flywheel casting blanks are to be polished, the clamping mechanism needs to be replaced, and the process is relatively complicated. b. The existing polishing mechanism can only polish a certain specification of automobile flywheel casting blank. When polishing automobile flywheel casting blanks with different diameters, the polishing mechanism needs to be replaced, which reduces the polishing efficiency in the polishing operation process.

[0004] In the above patent, the casting is clamped by the clamping mechanism, which can be used for fixing different specifications of automobile flywheel casting blanks. However, in the process of use, when the special-shaped blank casting is clamped, a large gap is generated between the clamping mechanism and the special-shaped blank casting, which causes the special-shaped blank casting to shake easily during polishing, reduces the fixing effect of the blank casting, and the inner side of the blank casting is prone to burrs. Generally, the polishing rod is inserted into the inner side of the blank to polish the blank. When the polishing rod is inserted into the inner side of the blank for processing, the burr is not polished completely due to the vibration of the polishing rod during the contact between the polishing rod and the burr, or the blank casting is excessively polished when the polishing rod is excessively forced, which reduces the processing effect of the blank casting.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] Firstly, this invention uses a clamping assembly to clamp irregularly shaped casting blanks. The clamping assembly makes multi-point contact with the surface of the irregularly shaped casting, increasing the fixing effect of the casting. Furthermore, the grinding assembly can grind the surface of the casting, and the grinding wheel in the grinding assembly can enter the interior of the irregularly shaped casting to grind away the burrs inside. At the same time, the grinding wheel can move according to the inner wall of the irregularly shaped casting, which can effectively grind both the surface and the interior of the casting, improving the processing effect.

[0031] Secondly, in this invention, the clamping assembly serves to clamp the irregularly shaped casting. Two cylinders can push two control plates closer or further apart. The clamping seat one between the two control plates can clamp the irregularly shaped casting, while the clamping seat two at the bottom can support the bottom of the irregularly shaped casting, improving the effect of fixing the irregularly shaped casting. The push rods inside the clamping seat one and clamping seat two can extend and retract, allowing the push rods to return to a fixed extension length. At the same time, the spring can push the push rods against the surface of the workpiece, and then current is transmitted to the electromagnet. The electromagnet fixes the extension length of the push rods. The push rods extend to different lengths, and the push rods will distribute and support the irregularly shaped casting along the surface of the workpiece.

[0032] Thirdly, in this invention, the grinding component plays a grinding role, which can grind the burrs inside the irregularly shaped casting. The linear motor can control the sliding plate to slide, and the sliding plate will drive the fixed sleeve to extend from the limit seat, so that the grinding wheel can enter the interior of the irregularly shaped workpiece. The control seat is fixed inside the irregularly shaped casting by multiple sets of hydraulic cylinders. The position of the grinding wheel is controlled by the hydraulic cylinders, so that the grinding wheel can move along the inner wall of the irregularly shaped workpiece to grind the burrs inside the irregularly shaped casting.

[0033] Fourthly, in this invention, the grinding component can also be used for grinding burrs on the surface of irregularly shaped castings. The linear motor can control the slide plate to slide, and the slide plate will drive the fixed sleeve to retract into the limit seat. Then, the position of the control seat is fixed by the hydraulic cylinder, and the grinding wheel is fixed. Then, the casting is moved by the clamping component to grind the surface of the casting.

[0034] Fifth, in this invention, the adsorption ring plays the role of controlling the rotating frame and can fix the rotation angle of the rotating frame. The adsorption ring is made of an electromagnet. When the adsorption ring is energized, it can generate magnetic force and adsorb the lower end face of the rotating frame to fix the rotating frame, thereby preventing the rotating frame from rotating during the processing of the clamping component and increasing the fixing effect of the clamping component.

[0047] In this embodiment of the invention, a grinding machine for irregularly shaped blanks is described. Please refer to [link to relevant documentation]. Figure 1 - Figure 8 The device includes a platform 1, a rotating frame 3 rotatably mounted on the upper end of the platform 1, and a fixed frame 5 installed on the upper end of the platform 1. The device is characterized in that it also includes a clamping assembly 4, which is mounted on the rotating frame 3.

[0048] Grinding component 7, with slide rail 2 6 at the bottom, which is fixed to the fixing frame 5;

[0049] The grinding assembly 7 includes a slide plate 701 and a fixed plate 702. The fixed plate 702 is fixed on the fixed frame 5. The slide plate 701 is vertically slidably mounted on the slide rail 6. A linear motor 703 is mounted on the outer wall of the fixed plate 702. The output end of the linear motor 703 is fixedly connected to the outer wall of the slide plate 701. A second motor 704 is mounted on the outer wall of the slide plate 701. The output end of the second motor 704 is connected to a belt. The belt is connected to a first transmission wheel 706. A second transmission wheel 715 is mounted on the inner side of the first transmission wheel 706. A transmission rib 713 is mounted on the inner side of the second transmission wheel 715. A fixed sleeve 705 is fitted on the outside of the transmission rib 713. A grinding wheel fixing seat 710 is mounted on the end of the transmission rib 713 away from the second transmission wheel 715. A grinding wheel 708 is fitted on the outside of the grinding wheel fixing seat 710.

[0050] The clamping assembly 4 clamps irregularly shaped workpieces and can fix workpieces with various bending angles. The grinding assembly 7 grinds the clamped workpieces and can grind the surface or interior of the workpieces to improve the processing effect. The linear motor 703 drives the slide plate 701 to reciprocate. The slide plate 701 drives the fixed sleeve 705 to move together and controls the extension length of the grinding wheel 708 at one end of the fixed sleeve 705 so that the grinding wheel 708 can enter the interior of the workpiece to grind the interior. The second motor 704 drives the transmission rib 713 to rotate through the first transmission wheel 706 and the second transmission wheel 715. The transmission rib 713 drives the grinding wheel fixing seat 710 and the grinding wheel 708 to move together.

[0051] A motor 8 is installed at the bottom of the platform 1, and the output end of the motor 8 is fixedly connected to the center of the bottom of the rotating frame 3.

[0052] Motor 8 controls the rotation angle of the rotating frame 3, enabling the rotating frame 3 to control the angle of the clamping assembly 4, thus facilitating the control of the workpiece clamping angle of the clamping assembly 4.

[0053] An annular groove is provided on the upper end face of the platform 1, and an adsorption ring 2 is provided in the groove on the upper end face of the platform 1. The adsorption ring 2 is located below the rotation path of the rotating frame 3.

[0054] The adsorption ring 2 serves to control the rotating frame 3 and fix the rotation angle of the rotating frame 3. The adsorption ring 2 is an electromagnet. When the adsorption ring 2 is energized, the adsorption ring 2 can generate magnetic force and adsorb the lower end face of the rotating frame 3 to fix the rotating frame 3, so as to prevent the rotating frame 3 from rotating during the processing of the clamping component 4 and increase the fixing effect of the clamping component 4.

[0055] The clamping assembly 4 includes two slide rails 401, which are symmetrically arranged above the rotating frame 3. A control plate 402 is slidably mounted on each of the two slide rails 401. A clamping seat 404 is provided on the adjacent surface of each of the two control plates 402. A cylinder 403 is provided on the outer wall of each of the two control plates 402. The cylinder 403 is fixed to the upper end surface of the rotating frame 3. A clamping seat 405 is provided at the upper end of the rotating frame 3.

[0056] The clamping assembly 4 serves to clamp the workpiece. The cylinder 403 controls the control plate 402, allowing the control plate 402 to slide on the slide rail 401. This allows the two control plates 402 to move away from or closer to each other. The clamping seat 404 between the two control plates 402 clamps the workpiece, and the clamping seat 405 supports the bottom of the workpiece, improving the workpiece's fixation effect.

[0057] Both clamping base 1 404 and clamping base 2 405 have an arc-shaped exterior and a hollow interior. Through holes are provided on the inner side of clamping base 1 404 and clamping base 2 405, and telescopic push rods are provided in the through holes of clamping base 1 404 and clamping base 2 405.

[0058] The push rods inside clamping seats 404 and 405 are telescopic and are controlled by a magnetic electromagnet. One end of the push rod is equipped with a spring. The spring and electromagnet are located inside clamping seats 404 and 405. The spring can reset the retracted push rod, so that when clamping seats 404 and 405 are not clamping or fixing the workpiece, the push rod can return to a fixed extension length. At the same time, the spring can press the push rod against the surface of the workpiece, and then current is transmitted to the electromagnet, which fixes the extension length of the push rod.

[0059] The fixed sleeve 705 has a hydraulic flow channel 714 inside. A control seat 709 is provided on the outside of the fixed sleeve 705 near the grinding wheel 708. The control seat 709 is hollow inside and has through holes around its perimeter. A hydraulic cylinder 711 is installed in the through holes around the control seat 709. A connecting pipe 712 is connected to the bottom of the hydraulic cylinder 711. The connecting pipe 712 is connected to one end of the hydraulic flow channel 714 inside the fixed sleeve 705.

[0060] The fixing sleeve 705 serves to fix the transmission rib 713. The transmission rib 713 is made of flexible steel bar and can be bent. The positions of the fixing sleeve 705 and the transmission rib 713 can be moved. The control seat 709 and the grinding wheel 708 at one end of the transmission rib 713 can enter the interior of the workpiece. The transmission rib 713 can rotate at the bending angle. The grinding wheel 708 grinds the interior of the workpiece. The hydraulic fluid channel 714 inside the fixing sleeve 705 is filled with hydraulic fluid. The hydraulic fluid is introduced into the hydraulic cylinder 711 through the hydraulic fluid channel 714 and the connecting pipe 712 to control the extension length of the hydraulic cylinder 711. The extended end of the hydraulic cylinder 711 can press against the interior of the workpiece to fix the position of the grinding wheel 708, which facilitates the grinding wheel 708 to grind.

[0061] It also includes a hydraulic fluid guide valve 716, which is sleeved on the outside of the fixed sleeve 705. The outer wall of the fixed sleeve 705 has a through hole, and the external through hole of the fixed sleeve 705 is connected to the hydraulic flow channel 714. The external through hole of the fixed sleeve 705 is connected to the hydraulic fluid guide valve 716.

[0062] The hydraulic guide valve 716 controls the flow of hydraulic fluid. The hydraulic guide valve 716 controls different amounts of hydraulic fluid to enter different hydraulic fluid channels 714. The hydraulic guide valve 716 controls the hydraulic fluid to enter different hydraulic cylinders 711, thereby controlling the different hydraulic cylinders 711 to extend to different lengths. When the hydraulic cylinders 711 around the workpiece can extend to different lengths, the position of the control seat 709 inside the workpiece is controlled. The control seat 709 and the grinding wheel 708 can move along the inner wall of the workpiece to grind the inside of the workpiece.

[0063] It also includes a limiting seat 707, which is fixed to the outer wall of the slide plate 701. The outer wall of the limiting seat 707 has a through hole corresponding to the position of the fixing sleeve 705, and an annular protrusion is provided at the position of the through hole on the outer wall of the limiting seat 707.

[0064] The limiting seat 707 serves to restrict the position of the fixed sleeve 705. When the fixed sleeve 705 retracts into the limiting seat 707, it restricts the position of the fixed sleeve 705 and the control seat 709, preventing the control seat 709 and the fixed sleeve 705 from shifting when they retract into the limiting seat 707.

[0065] The inner diameter of the protruding through hole on the limit seat 707 is smaller than the outer diameter of the control seat 709.

[0066] The limiting seat 707 can enter the protruding through hole of the limiting seat 707. At the same time, the hydraulic fluid is controlled by the hydraulic guide valve 716 to enter all the hydraulic cylinders 711. The hydraulic cylinders 711 will press against the inner wall of the protruding through hole on the limiting seat 707, fixing the position of the control seat 709 and the grinding wheel 708, so that the grinding wheel 708 can grind the outside of the workpiece.

[0067] The control seat 709 has a uniform groove on the side near the grinding wheel 708, and a ball bearing 718 is provided in the groove on the outer wall of the control seat 709.

[0068] The groove on one side of the control seat 709 serves to accommodate the ball bearing 718. The ball bearing 718 presses against the un-grinded area of ​​the grinding wheel 708, increasing the stability of the rotation of the grinding wheel 708.

[0069] The working principle of this invention is as follows: When in use, the control plate 402 is moved by the cylinder 403, allowing the clamping seat 404 inside the control plate 402 to fix the irregularly shaped casting. The bottom of the casting is supported by the clamping seat 405. The push rods inside the clamping seats 404 and 405 are fixed in length by an electromagnet. The push rods inside the clamping seats 404 and 405 are distributed and supported along the surface of the irregularly shaped casting, thus fixing it in place. Then, the device is activated. Motor 8 drives the rotating frame 3 to rotate and controls the angle of the fixed casting on the rotating frame 3. At the same time, it can control the synchronous movement of two control plates 402 through two cylinders 403 to control the position of the casting. When the casting moves to the appropriate position, the adsorption ring 2 generates magnetic force when energized. The adsorption ring 2 can adsorb the lower end face of the rotating frame 3 and fix the rotating frame 3, so as to prevent the rotating frame 3 from rotating during the processing of the clamping component 4 and increase the fixing effect of the clamping component 4.

[0070] When it is necessary to grind the burrs inside the casting, the linear motor 703 is started. The linear motor 703 controls the sliding plate 701 to slide. The sliding plate 701 drives the fixed sleeve 705 to extend from inside the limit seat 707, allowing the grinding wheel 708 to enter the interior of the irregularly shaped workpiece. The control seat 709 is fixed inside the irregularly shaped casting by multiple sets of hydraulic cylinders 711. Then, the hydraulic fluid is introduced into different hydraulic fluid channels 714 through the hydraulic guide valve 716. The hydraulic fluid channels 714 introduce the hydraulic fluid into different hydraulic cylinders 711, controlling the hydraulic cylinders 711 to extend to different lengths. At this time, the control seat 709 will move towards the retracted hydraulic cylinder 711, thus starting the motor 702. 4. Motor 2 704 drives transmission rib 713 to rotate through transmission wheel 1 706 and transmission wheel 2 715. Transmission rib 713 drives grinding wheel 708 to rotate together through grinding wheel fixing seat 710. At this time, grinding wheel 708 can approach the burr part inside the casting and grind the burr. The position of grinding wheel 708 is controlled by hydraulic cylinder 711 so that grinding wheel 708 can move along the inner wall of the irregular workpiece to grind the burr inside the irregular casting. After grinding is completed, motor 2 704 is turned off, and hydraulic cylinder 711 is fully retracted into control seat 709 through hydraulic guide valve 716 so that control seat 709 can be moved out of the casting normally.

[0071] When it is necessary to grind the burrs on the outside of the casting, start the linear motor 703. The linear motor 703 can control the slide plate 701 to slide. The slide plate 701 will drive the fixed sleeve 705 to retract into the limit seat 707. Then, the hydraulic cylinder 711 fixes the position of the control seat 709 and fixes the grinding wheel 708. Then, start the second motor 704. The second motor 704 will drive the grinding wheel 708 to rotate through the first transmission wheel 706, the second transmission wheel 715 and the grinding wheel fixing seat 710. Then, the clamping assembly 4 controls the casting to move, so that the casting comes into contact with the rotating grinding wheel 708. The grinding wheel 708 grinds the burrs on the surface of the casting. After grinding is completed, turn off the second motor 704 and remove the ground casting from the clamping assembly 4.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
