Referring to fig. 1, a cylinder clamping assembly provided in an embodiment of the invention is used for clamping a cylinder part, the cylinder part has a first end and a second end opposite to each other, and the cylinder clamping assembly includes:
the table top is used for bearing the cylindrical part;
a first support block 1 detachably connected to the first end for fixing the first end to the table top;
the second clamp 2 comprises a first clamping plate 21 and a second clamping plate 22, the first clamping plate 21 is detachably connected with the second clamping plate 22, the first clamping plate 21 and the second clamping plate 22 are mutually close to clamp a second end, and the second end is fixed on the table top through the second clamp 2.
Referring to fig. 1 to 4, in this embodiment, the first supporting block 1 is flat and is placed on the table top in a vertical state, and the first supporting block 1 is attached to the end face of the first end of the cylindrical part through a flat surface. In this embodiment, threaded connection is selected and mutually fixed after assembly.
First, the first end of the cylindrical member is supported by the first support block 1 assembled with the first end. The second end of the cylindrical part is then placed over the first clamping plate 21 and the second clamping plate 22 is then placed over the second end of the cylindrical part. Finally, the first clamping plate 21 and the second clamping plate 22 are assembled to clamp the second end of the cylindrical part, so that the stability in processing is ensured. In this embodiment, the first supporting block 1 and the second fixture 2 are used to clamp and position the cylindrical part together, so that both ends of the cylindrical part are supported, and the problem of shake generated during processing of the cylindrical part is avoided.
Meanwhile, the first support block 1 can be prevented from rotating in the machining process in a threaded connection mode with the end face of the first end portion of the cylindrical part, and the stability in machining is improved. And the second clamp 2 can have more contact area with the second end of the cylindrical part through the connection mode of clamping the second end of the cylindrical part by two clamping plates, so that the support of the second clamp 2 to the cylindrical part is firmer.
And after the processing is finished, the first supporting block 1 and the second clamp 2 can be disassembled, and the next cylindrical part to be processed is clamped again. Simultaneously, a plurality of sets of first supporting blocks 1 and second clamps 2 can be prepared, cylinder parts to be processed are clamped in advance, and after the processing of the previous cylinder part is finished, the next cylinder part to be processed which is clamped is placed on a table top for processing. And the first supporting block 1 and the second clamp 2 do not need to wait in the time of clamping after being disassembled, so that the processing efficiency is improved.
In an embodiment, the first support block 1 also has a side surface 13, through which side surface 13 the first support block 1 abuts the table top.
As shown in fig. 1 and 5, after the first support block 1 and the cylindrical part are clamped, a side surface 13 is arranged below the first support block 1. The two sides of the side surface 13 are respectively provided with a first surface 11 and a second surface 12, and the first supporting block 1 is attached to the cylindrical part through the first surface 11 and then connected. When the first supporting block 1 is successfully clamped on the cylindrical part, the cylindrical part is placed on the table top. The side surface 13 of the first support block 1 is in contact with the table top, and the side surface 13 is closely fitted to the table top because the side surface 13 is parallel to the table top.
During processing, when the cylindrical part is subjected to force and transmits the force to the first support block 1, the first support block 1 in turn transmits the force to the table top via the side surfaces 13. Because the side surfaces 13 are parallel to the table top, the first support block 1 will not rotate when subjected to a force.
In an embodiment, the first supporting block 1 is cylindrical and extends along the axis of the cylindrical part, the first supporting block 1 has a plurality of side surfaces 13 distributed along the circumferential direction, the cylindrical part has a plurality of processing positions distributed along the circumferential direction, and when the first supporting block 1 is connected with the first end, the first supporting block 1 can rotate to enable each side surface 13 to abut against the table top one by one, so that each processing position is converted to a position parallel to the table top one by one for processing.
Referring to fig. 6, the solid line portion of the outer frame is the outline of the first supporting block 1, and the dotted line portion of the inner frame is the position of the machined surface of the cylindrical part. The position indicated at A in the figure is the surface at the time of machining, and each machining position of the cylindrical part needs to be rotated to the position at A for machining. In the figure, the position B is the position where the first supporting block 1 is abutted against the table top, and when the first supporting block 1 rotates to enable the side surfaces 13 to be located at the position B and abutted against the table top one by one, the first supporting block 1 also drives the cylindrical part to rotate to enable the processing positions to be switched to the position A one by one, so that the processing of the whole cylindrical part is completed.
Referring to fig. 2 and 6, the first supporting block 1 in this embodiment is a pentagonal column with five side surfaces 13. Correspondingly, the cylindrical part in this embodiment has five machining stations, and each machining station has a side surface 13 corresponding thereto. When each side surface 13 is at the B position, the corresponding side surface 13 is at the a position for machining. The processing position of the cylindrical part is the position on the surface of the cylindrical part, which needs to be processed, and the cylindrical part becomes a processing surface after the processing is completed.
Although the five processing surfaces of the cylindrical member are connected in sequence to form a pentagon, the pentagon of the first support block 1 does not coincide with the pentagon of the cylindrical member. So that when the side surface 13 of the first support block 1 is attached to the table surface downward, the corresponding parallel processing surface is processed upward.
When the first support block 1 is in contact with the table top via the first side surface 13, the corresponding first machining position on the cylindrical part is arranged in a direction away from the table top, which facilitates machining. After the first surface to be machined is machined, the first supporting block 1 is rotated to enable the second side surface 13 on the first supporting block 1 to be in contact with the table top, and then a second machining position on the cylindrical part is arranged in the direction away from the table top for machining. And by analogy, the cylindrical part can be taken down until all surfaces to be processed on the cylindrical part are processed, and the cylindrical part to be processed next time is placed for processing.
In an embodiment, the cylinder clamping assembly further comprises an electromagnet for fixing the first support block 1 and the second clamp 2 to the table top. In this embodiment, the first supporting block 1 and the second fixture 2 are made of ferromagnetic metal materials, so that the structural strength is improved and the service life is prolonged. The electromagnet is arranged in the table top, and the table top is magnetic through the electromagnet. And the existence of electromagnetic ferromagnetism can be controlled by on/off power.
And after the first supporting block 1 and the second clamp 2 are clamped with the cylindrical part to be processed, the cylindrical part to be processed is placed on a table top. At the moment, the electromagnet is electrified to have magnetism, and the electromagnet firmly adsorbs the first supporting block 1 and the second clamp 2 on the table top through magnetism, so that the first supporting block 1 and the second clamp 2 are kept stable during processing. And after the processing is finished, the power is cut off, so that the electromagnet is nonmagnetic. At this time, the machined cylindrical part can be removed, and the next clamped part to be machined can be replaced on the table top. Finally, the previous operation is repeated, and power-on is performed.
Meanwhile, the electromagnet can be arranged at a fixed position on the table top, so that the fixed position on the table top has magnetism. The first supporting block 1 and the second clamp 2 are fixed on the table top through magnetic attraction, so that the first supporting block 1 and the second clamp 2 are also positioned, the relative positions of each cylindrical part and the table top are kept fixed, and the machining is accurate and convenient.
In an embodiment, the first support block 1 has a first surface 11 and a second surface 12 opposite to each other, the first surface 11 is provided with a mounting hole penetrating the first surface 11 and the second surface 12, and the first support block 1 is fixedly connected to the first end portion.
In this embodiment, the first end of the cylindrical part is provided with a machining allowance zone. The machining allowance zone is a part which needs to be cut off in subsequent machining, so that the end face of the first end part is provided with a screw hole, and the formed product is not affected.
As shown in fig. 2, the first supporting block 1 is plate-shaped, and the surface is provided with mounting holes, and the types of the mounting holes include screw holes and through holes. The position of the mounting hole is aligned with the position of the screw hole on the end face of the first end part, so that the bolt can pass through the mounting hole and the screw hole at the same time. The first supporting block 1 is in threaded connection with the first end, so that the connection is firm and the disassembly is convenient.
In one embodiment, the surface of the first clamping plate 21 facing the second clamping plate 22 is semicircular.
As shown in fig. 3, the first clamping plate 21 approximates a groove shape with two sides high and a middle low. The first clamping plate 21 is in contact with the cylindrical member and is an inner surface. The outer surface of the cylindrical member is circular, so that the inner surface defined by the main body 211 and the extension 212 is semicircular, and the radius of the semicircle is equal to the radius of the cylindrical member. The cylindrical part is attached to the first clamping plate 21 so that the contact area is maximized. Thereby reducing the pressure intensity received during processing and prolonging the service life.
In an embodiment, the first clamping plate 21 includes a main body 211 and an extension 212, and a line connecting an outer surface of the main body 211 and an outer surface of the extension 212 is a fold line.
As shown in fig. 3, the first clamping plate 21 needs to be an outer surface in contact with the table top because the second end of the cylindrical part is supported by the first clamping plate 21 and the first clamping plate 21 is supported by the table top; to prevent rotation during machining, the outer surface of the first clamping plate 21 also needs to have a surface parallel to the table top, providing better support during machining of the cylindrical part. The cylindrical member is rotated to a different surface for machining, and the outer surface in contact with the table surface is transferred from the main body 211 to the extension 212 during rotation. Therefore, the connection line between the outer surface of the main body 211 and the outer surface of the extension 212 is a broken line, so that both the main body 211 and the extension 212 can provide good support.
In one embodiment, the first clamping plate 21 is axisymmetric with the second clamping plate 22.
As shown in fig. 3, the inner surface of the second clamping plate 22 is also semicircular, and is enclosed in a circular shape together with the first clamping plate 21, thereby wrapping the entire cylindrical member. In the case where the cylindrical member is required to be rotated during processing, the cylindrical member can be fitted to the first clamping plate 21 or the second clamping plate 22 regardless of the rotation of the cylindrical member.
In an embodiment, the extension portion 212 is provided with a second through hole along a direction towards the second clamping plate 22, and the extension portion 212 is in threaded connection with the second clamping plate 22.
Referring to fig. 1 and 3, after the second end of the cylindrical member is placed on the first clamping plate 21, the second clamping plate 22 is covered on the second end of the cylindrical member, so that the second clamping plate 22 and the first clamping plate 21 are aligned with each other. Finally, the bolts simultaneously pass through the second through holes of the first clamping plate 21 and the second clamping plate 22, so that the first clamping plate 21 and the second clamping plate 22 clamp the second end part of the cylindrical part.
Another embodiment of the present invention also provides a machining apparatus, including a machining assembly and a cylinder clamping assembly as described above, the cylinder clamping assembly being used for clamping and positioning a cylinder part, the machining assembly being used for machining the cylinder part.
In this embodiment, when the first supporting block 1 is clamped to the first end of the cylindrical part, the second clamp 2 is clamped to the second end of the cylindrical part, and is placed on the table top. The electromagnet is electrified to firmly adsorb the first supporting block 1 and the second clamp 2 on the table top. And (5) positioning the cylindrical part on the table top is completed. And then starting the processing assembly, and processing the cylindrical part by the processing assembly. After finishing processing, the electromagnet is powered off, and the cylindrical part which is finished to be processed is taken out and put into the next cylindrical part to be processed.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
