Description

Technical Field

[0001] The invention relates to the technical field of deburring, in particular to a casting blank deburring device. Background Art

[0002] Casting blanks refer to semi-finished products obtained through casting during the casting process. These semi-finished products need to undergo subsequent processing after casting.

[0003] For tubular casting blanks, cutting and other processing are usually required. After cutting, there will be a lot of burrs on the ends of the tubular casting blanks. In order not to affect the use, the burrs on the ends (especially the inner edge and the outer edge) need to be polished. In the prior art, for example, in the patent document with publication number "CN118238010A", by setting structures such as a cone head, a first grinding disc, a rotating plate and a second grinding disc, the inner and outer edges of the ends of the tubular castings can be polished at the same time to remove the burrs. However, in this technical solution, when deburring tubular casting blanks with the same inner and outer diameters, the inner edge of the tubular casting blank is always in contact with the first grinding disc on the outer wall of the cone head at the same position, and the first grinding disc wears out very quickly, has a low service life, and needs to be replaced frequently. Summary of the invention

[0004] The object of the present invention is to provide a casting blank deburring device to solve the above-mentioned defects of the prior art.

[0005] The present invention is achieved through the following technical solutions:

[0006] A casting blank deburring device comprises a clamping mechanism and a grinding mechanism for clamping the casting blank, wherein the grinding mechanism comprises:

[0007] Two symmetrically arranged inner grinding heads are used to grind the inner edge of the casting blank. The inner grinding heads rotate around the symmetrical center line to form a conical structure.

DETAILED DESCRIPTION

[0028] refer to Figure 1 A casting blank deburring device includes a clamping mechanism 1 and a grinding mechanism 2 for clamping a casting blank 4. In practical applications, the clamping mechanism 1 and the grinding mechanism 2 are installed on the top of a workbench 3.

[0029] refer to Figure 2The grinding mechanism 2 includes two symmetrically arranged inner grinding heads 201, a first adjusting component 202, two symmetrically arranged outer grinding heads 203, a second adjusting component 204 and a turntable 205. The inner grinding head 201 is used to grind the inner edge of the casting blank 4, and the outer grinding head 203 is used to grind the outer edge of the casting blank 4. The inner grinding head 201 rotates around the symmetry center line for one circle to form a conical structure, and the outer grinding head 203 rotates around the symmetry center line for one circle to form a conical structure. It should be understood that the inner grinding head 201 and the outer grinding head 203 are arranged in a staggered manner to avoid interference. The first adjusting component 202 is used to drive the two inner grinding heads 201 to move closer to or away from each other, that is, to adjust the distance between the two inner grinding heads 201, and the second adjusting component 204 is used to drive the two outer grinding heads 203 to move closer to or away from each other, that is, to adjust the distance between the two outer grinding heads 203. The first adjusting component 202 and the second adjusting component 204 are mounted on a rotating disk 205, and the rotating disk 205 is connected to a first driving component 206 for driving the rotating disk 205 to rotate, that is, when the first driving component 206 drives the rotating disk 205 to rotate, it can drive the inner grinding head 201 and the outer grinding head 203 to rotate synchronously, and grind and remove burrs from the inner and outer edges of the casting blank 4. It should be understood that the axis of the rotating disk 205, the symmetric center lines of the two inner grinding heads 201, and the symmetric center lines of the two outer grinding heads 203 should be coaxial, and at the same time, should also be coaxial with the axis of the casting blank 4.

[0030] On the basis of the above, for the casting blank 4 of the same specification, by adjusting the distance between the two inner grinding heads 201 and the distance between the two outer grinding heads 203, the inner edge of the casting blank 4 can contact different positions of the inner grinding head 201 and the outer edge can contact different positions of the outer grinding head 203, thereby making full use of various parts of the inner grinding head 201 and the outer grinding head 203, increasing the service life of the inner grinding head 201 and the outer grinding head 203, and avoiding frequent replacement.

[0031] In addition, it can also adapt to casting blanks 4 with different inner diameters and outer diameters (including casting blanks 4 with the same thickness but different inner and outer diameters, and casting blanks 4 with different thicknesses), and can also selectively grind and remove burrs only on the inner edge or outer edge of the casting blank 4. It is easy to understand that when only the inner edge of the casting blank 4 is ground, the two outer grinding heads 203 are moved away from each other to the maximum distance, so that the outer edge of the casting blank 4 cannot contact the outer grinding heads 203, and only the inner edge of the blank contacts the inner grinding head 201; conversely, when only the outer edge of the casting blank 4 is ground, the two inner grinding heads 201 are moved close to each other to the minimum distance, so that the inner edge of the casting blank 4 cannot contact the inner grinding head 201, and only the outer edge of the blank contacts the outer grinding head 203.

[0032] As an option, in this embodiment, the first driving component 206 is a motor that drives the turntable 205 to rotate after being decelerated by a gear reduction structure. In other embodiments, of course, the motor can also be driven to rotate the turntable 205 after being decelerated by other reduction structures (such as belt reduction).

[0033] refer to Figure 3 and Figure 4 In this embodiment, the inner grinding head 201 includes an inner grinding block 2012 and an inner grinding seat 2011, and the inner grinding block 2012 is connected to the inner grinding seat 2011 through a fastener; the outer grinding head 203 includes an outer grinding block 2032 and an outer grinding seat 2031, and the outer grinding block 2032 is connected to the outer grinding seat 2031 through a fastener; such a configuration facilitates the replacement of the inner grinding block 2012 and the outer grinding block 2032. In practical applications, a limiting groove can be provided on the inner grinding seat 2011, and the inner grinding block 2012 is placed in the limiting groove and then connected to the inner grinding seat 2011 through a fastener; similarly, a limiting groove can be provided on the outer grinding seat 2031, and the outer grinding block 2032 is placed in the limiting groove and then connected to the outer grinding seat 2031 through a fastener. The above-mentioned fasteners are preferably screws. On this basis, countersunk holes are set on the inner grinding block 2012 and the outer grinding block 2032, and threaded holes are correspondingly set on the inner grinding seat 2011 and the outer grinding seat 2031.

[0034] As an option, in this embodiment, the first adjustment component 202 includes a first U-shaped seat, a first guide rail, a first screw rod and two first sliders, the first U-shaped seat is fixedly connected to the turntable 205, the first screw rod is rotatably arranged on the first U-shaped seat, the two ends of the first screw rod are respectively threaded with a first slider, and the threads at the two ends of the first screw rod are opposite in rotation, the first guide rail is fixedly arranged on the first U-shaped seat, the two first sliders are slidably matched with the first guide rail, that is, the first guide rail limits the two first sliders to rotate around the first screw rod, when the first screw rod rotates forward or reversely, the two first sliders can approach or move away from each other, and the two inner grinding heads 201 are each fixedly connected to a first slider, so as to follow the two first sliders to approach or move away from each other. In practical applications, one end of the first screw rod is connected to a driving element (not shown, such as a knob, a motor, etc.) to drive the first screw rod to rotate. In addition, it is easy to understand that in other embodiments, the first adjustment component 202 can certainly be in other forms, such as respectively setting a driving structure (such as an electric push rod, a linear motor, etc.) to adjust the position of the two first sliders.

[0035] As an option, in this embodiment, the second adjustment component 204 includes a second U-shaped seat, a second guide rail, a second screw rod and two second sliders, the second U-shaped seat is fixedly connected to the turntable 205, the second screw rod is rotatably arranged on the second U-shaped seat, the two ends of the second screw rod are respectively threaded with a second slider, and the threads at the two ends of the second screw rod are opposite, the second guide rail is fixedly arranged on the second U-shaped seat, the two second sliders are slidably matched with the second guide rail, that is, the second guide rail limits the two second sliders to rotate around the second screw rod, when the second screw rod rotates forward or reversely, the two second sliders can be close to or away from each other, and the two outer grinding heads 203 are each fixedly connected to a second slider, so as to follow the two second sliders to move closer to or away from each other. In practical applications, one end of the second screw rod is connected to a driving element (not shown, such as a knob, a motor, etc.) to drive the second screw rod to rotate. In addition, it is easy to understand that in other embodiments, the second adjustment component 204 can certainly be in other forms, such as respectively setting a driving structure (such as an electric push rod, a linear motor, etc.) to adjust the position of the two second sliders.

[0036] refer to Figure 2 and Figure 4 In this embodiment, the grinding mechanism 2 further includes an end face grinding head 207 for grinding the end face of the casting blank 4. The end face grinding head 207 is connected to a second driving component 208 for driving it to approach or move away from the end face of the casting blank 4. As an option, the second driving component 208 in this embodiment is an electric push rod. In other embodiments, the second driving component 208 can of course also be in other forms.

[0037] It is worth noting that the end face grinding head 207 should have a certain length along the radial direction of the casting blank 4, so as to adapt to the casting blanks 4 of different thicknesses and diameters. A third driving component (not shown) can also be provided to drive the second driving component 208 to adjust the position along the radial direction of the casting blank 4, so that the end face grinding head 207 can adapt to the diameter and thickness changes of the casting blank 4. In addition, the end face grinding head 207 can also include an end face grinding seat (not shown) and an end face grinding block (not shown) like the inner grinding head 201 and the outer grinding head 203, and the two are fastened to facilitate replacement.

[0038] refer to Figure 5In this embodiment, the clamping mechanism 1 includes two clamping blocks 101 for clamping the casting blank 4 and a third adjusting component 102 for driving the two clamping blocks 101 to move away from or towards each other. It should be understood that the two clamping blocks 101 move away from or towards each other to achieve clamping of casting blanks 4 of different diameters. Furthermore, in this embodiment, the two clamping blocks 101 are in an arc-shaped structure, which is convenient for automatic centering when clamping casting blanks 4 of different diameters. In other embodiments, the two clamping blocks 101 may also be in a V-shaped structure, which may also achieve automatic centering. The specific structure of the third adjusting component 102 is not limited, for example, it may be in the same manner as the first adjusting component 202 and the second adjusting component 204.

[0039] The clamping mechanism 1 also includes a positioning component 103, which includes a positioning seat 1031 and a positioning plate 1032. The positioning seat 1031 is fixedly arranged at one end of the clamping block 101 away from the grinding mechanism 2, and the positioning plate 1032 limits the axial displacement of the casting blank 4 during grinding and deburring. Furthermore, the positioning plate 1032 is connected to an adjusting screw 1033, which is threadedly connected to the positioning seat 1031. By rotating the adjusting screw 1033, the position of the positioning plate 1032 can be adjusted to adapt to casting blanks 4 of different lengths.

[0040] The clamping mechanism 1 further includes an axial driving component 104 for driving the third adjusting component 102 to approach or move away from the grinding mechanism 2. The specific structure of the axial driving component 104 is not limited, for example, a linear slide, an electric push rod, or a screw nut pair can be used.
