Description
Technical Field

[0002] With the continuous development and progress of the manufacturing industry, the demand for mechanical processing has become increasingly diversified and complex. In actual production, the shapes, sizes and materials of the parts to be processed are different, so different clamping structures are required to clamp parts of different shapes.
[0003] The existing multi-purpose clamping structure for mechanical processing clamps the parts through the side fixing device when clamping relatively regular parts, while it is necessary to clamp the parts through a combined clamping structure or a customized fixture when clamping irregularly shaped parts. The combined clamping structure can adapt to the irregular shape of the parts by flexibly adjusting the position and angle of these clamping elements, while the customized fixture needs to be specially designed and manufactured according to the specific shape and processing requirements of the irregular parts.
[0004] When existing multi-purpose clamping structures for mechanical processing clamp parts with similar cylindrical or conical structures, the parts are mostly clamped by two clamping blocks. Since the clamping surfaces of the two clamping blocks are mostly parallel surfaces, the contact area between the clamping surfaces and the outer wall of the curved surface of the part is small. When a small force is applied for clamping during the part processing, slipping is likely to occur, and the curved surface cannot be effectively clamped. When a large force is applied for clamping, the outer wall of the part is easily damaged. In addition, the curvature of the curved surfaces of different parts is different, and the clamping blocks cannot adapt to the outer walls of the curved surfaces of different parts, resulting in a small clamping contact area.

When placing the part with a curved surface on the support seat, drive cylinder 2 to push the support seat, so that the sliding plate at the bottom of the support seat slides on the slide rail.

DETAILED DESCRIPTION
[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0031] Embodiment 1
[0032] like Figure 1-6 As shown, a multi-purpose clamping structure for mechanical processing and a method of use of the embodiment of the present invention include a base 1, a processing base plate 2 is arranged on the top of the base 1, a support seat 3 is arranged on the top of the processing base plate 2, a curved surface clamp 4 is arranged on the support seat 3, an adjustment structure 5 is arranged on the support seat 3, the adjustment structure 5 is used to adjust the angle of the curved surface clamp 4, a fixed clamp block 6 is movably installed on the bottom of the support seat 3, a driving structure 7 is arranged on the support seat 3, and the driving structure 7 is used to control the reciprocating motion of the fixed clamp block 6.
[0033] Specifically, when clamping parts with a column or cone structure, the existing multi-purpose clamping structure for machining can clamp the parts through the side fixture. However, when clamping the curved side, the contact area between the clamping block in the existing fixture and the curved side of the part is small, which is prone to slippage during the machining of the part, and the curved surface cannot be effectively clamped. The inclination of the curved surface of different parts is different, and the existing fixture cannot adjust the angle between the fixture and the curved surface of the part.
[0034] In this embodiment, when clamping a part with a curved surface, the part is first placed on the processing base plate 2 on the top of the base 1, and the angle between the curved surface fixture 4 on the support seat 3 and the curved surface of the part is adjusted by adjusting the structure 5, so that the curved surface clamping part of the curved surface fixture 4 is in contact with the curved surface of the part as much as possible, thereby increasing the clamping area between the two, avoiding slipping during processing of the part and causing the part to fall off the fixture, and then the curved surface fixture 4 is clamped to the part through the driving action in the adjustment structure 5, so as to clamp the curved surface of the part. When clamping relatively regular parts, the parts are fixed by the fixed clamping block 6 at the bottom of the support seat 3. Since the sizes of different parts are different, the distance between the fixed clamping blocks 6 is adjusted by the driving structure 7, so as to better clamp and fix parts of different sizes.
[0035] like Figure 1 As shown, the curved surface clamp 4 is semi-circular, there are two curved surface clamps 4, and the curved surface clamps 4 are symmetrically arranged on the support seat 3, and the adjacent surfaces of the two curved surface clamps 4 are both provided with anti-slip rubber pads.
[0036] Specifically, when clamping and fixing one side of the curved surface of a part, the curved surface fixture 4 is designed to be semi-circular in order to better fit the curved surface of the part. By squeezing the anti-slip rubber pad, the contact area with the curved surface of the part can be increased, thereby improving the stability of the clamped part.
[0037] like Figure 2 As shown, the adjustment structure 5 includes a motor 501, which is fixedly mounted on a support seat 3, a base 502 is fixedly mounted on the support seat 3, a base 2 506 is fixedly mounted on the support seat 3, the output end of the motor 501 is rotatably mounted on the base 1 502, a rotating arm 503 is fixedly mounted on the output end of the motor 501, a telescopic inner tube 504 is rotatably mounted on the other end of the rotating arm 503, a telescopic sleeve 505 is rotatably mounted on the base 2 506, the interior of the telescopic sleeve 505 is a cavity structure, the telescopic inner tube 504 is slidably mounted inside the telescopic sleeve 505, a cylinder 1 507 is fixedly mounted on the outer side of the telescopic sleeve 505, and the output end of the cylinder 1 507 is fixedly connected to the curved surface fixture 4.
[0038] Specifically, when a part with a curved surface is placed on the support seat 3, the motor 501 is started, and the motor 501 drives the rotating arm 503 to rotate on the base 1 502. When the rotating arm 503 rotates, the rotating arm 503 pulls the telescopic inner tube 504 rotatably mounted therewith to move, and the telescopic inner tube 504 slides inside the telescopic sleeve 505. Since the telescopic sleeve 505 is rotatably mounted on the base 2 506, when the rotating arm 503 rotates, the telescopic inner tube 504 drives the telescopic sleeve 505 to rotate on the base 2 506. Because the cylinder 1 507 is fixedly mounted on one side of the telescopic sleeve 505, the output end of the cylinder 1 507 is fixedly connected to the curved surface clamp 4, so that the angle of the curved surface clamp 4 can be adjusted by rotating the telescopic sleeve 505. After clamping the part, starting the cylinder 1 507 can push the curved surface clamp 4 to apply a force in the direction of the processing base plate 2, so that the part is stably fixed on the processing base plate 2, thereby improving the clamping stability.
[0039] Embodiment 2
[0040] like Figure 1-3 As shown in the comparative example 1, another multi-purpose clamping structure for machining and the use method of the present invention are implemented as follows:
[0041] The support seat 3 is symmetrically arranged on the top of the processing base plate 2 . There are four fixed clamping blocks 6 , and the four fixed clamping blocks 6 are symmetrically arranged on one side of the bottom of the support seat 3 .
[0042] Specifically, when clamping a relatively regular part, the four corners of the part are clamped and fixed by the fixed clamping blocks 6 on the support seat 3 to prevent the part from falling off the processing base plate 2 when the part is processed.
[0043] like Figure 3 As shown, the driving structure 7 includes a cylinder 2 701, which is fixedly mounted on the processing base plate 2, and the output end of the cylinder 2 701 is fixedly connected to one side of the support seat 3. A slide rail 702 is fixedly mounted on the top of the processing base plate 2. There are four slide rails 702, and the slide rails 702 are symmetrically mounted on the processing base plate 2. Sliding plates 703 are slidably mounted on the slide rails 702, and the sliding plates 703 are fixedly mounted on the bottom of the support seat 3. A rotating rod 1 704 is rotatably mounted on the top of the support seat 3, and a rotating rod 2 705 is rotatably mounted on the other end of the rotating rod 1 704. The rotating rod 2 705 is rotatably mounted on the processing base plate 2, and both ends of the rotating rod 2 705 are rotatably connected to the rotating rod 1 704.
[0044] Specifically, when the parts are clamped and fixed, the sliding plate 703 at the bottom of the support seat 3 slides on the slide rail 702 through the driving action of the cylinder 2 701 in the driving structure 7. At the same time, the two support seats 3 are driven by the rotating rod 1 704 rotatably installed on the top and the rotating rod 2 705 rotatably installed on the processing base plate 2, so that the two support seats 3 are moved closer to or away from each other under the driving action of the cylinder 2 701, thereby realizing the driving of the support seat 3.
[0045] like Figure 3-5 As shown, a distance adjustment structure 8 is provided at the bottom of the support seat 3, and the distance adjustment structure 8 includes a motor 2 803, and the motor 2 803 is fixedly installed on the support seat 3, and a base 3 804 is fixedly installed on the support seat 3. A threaded shaft 801 is fixedly connected to the output end of the motor 2 803, and the threaded shaft 801 is rotatably installed on the base 3 804. Threads are provided at positions near both ends of the threaded shaft 801, and the threads provided at both ends of the threaded shaft 801 are screwed in opposite directions. The fixed clamp block 6 is threadedly installed on the thread of the threaded shaft 801, and an anti-slip pad 802 is fixedly installed on the fixed clamp block 6.
[0046] Specifically, while driving the support seat 3, the motor 2 803 in the distance adjustment structure 8 is driven to make the threaded shaft 801 rotate on the base 3 804. Since the threaded portion on the threaded shaft 801 of the fixed clamp block 6 is threadedly installed, and the threads set at both ends of the threaded shaft 801 are screwed in opposite directions, when the threaded shaft 801 rotates, the fixed clamp blocks 6 move closer to or farther away from each other on the threaded shaft 801, thereby achieving the clamping and fixing of the parts by the fixed clamp blocks 6. By arranging an anti-slip pad 802 on the fixed clamp block 6, the friction between the fixed clamp block 6 and the parts is increased, thereby preventing the parts from slipping on the fixed clamp block 6 during processing.
[0047] like Figure 6 As shown, a fixed base 14 is fixedly mounted on the base 1, and the fixed base 14 is symmetrically mounted on the base 1. A motor 3 9 is fixedly mounted on the base 1, and a base 4 10 is fixedly mounted on the base 1. The output end of the motor 3 9 is rotatably mounted on the base 4 10, and a bevel gear 11 is fixedly mounted on the output end of the motor 3 9, and one side of the bevel gear 11 is meshedly connected with a bevel gear 2 12. A rotating shaft 15 is rotatably mounted on the fixed base 14, and the bevel gear 2 12 is fixedly mounted on one end of the rotating shaft 15.
[0048] Specifically, when processing one side of a part, it is necessary to adjust the rotation of the part, start the motor three 9 on the base 1, and drive the bevel gear one 11 to rotate on the base four 10 through the motor three 9. Because the bevel gear two 12 and the bevel gear one 11 are meshed with each other, the bevel gear two 12 drives the rotating shaft 15 to rotate on the fixed base 14, thereby realizing the driving of the rotating shaft 15.
[0049] like Figure 6 As shown, a connecting block 13 is fixedly mounted on the rotating shaft 15 , and the connecting block 13 is fixedly connected to the processing base plate 2 .
[0050] Specifically, when the rotating shaft 15 rotates, the connecting block 13 is fixedly connected to the rotating shaft 15 , so that the connecting block 13 drives the processing base plate 2 to rotate.
[0051] A method for using a multi-purpose clamping structure for machining, specifically comprising the following steps:
[0052] When clamping a part with a curved surface, first place the part on the processing base plate 2 on the top of the base 1. When placing the part with a curved surface on the support seat 3, drive the second cylinder 701 to push the support seat 3, so that the sliding plate 703 at the bottom of the support seat 3 slides on the slide rail 702. At the same time, the two support seats 3 are driven by the rotating rod 1 704 rotatably installed on the top and the rotating rod 2 705 rotatably installed on the processing base plate 2, so that the two support seats 3 are close to each other under the driving action of the second cylinder 701, thereby realizing the driving of the support seats 3, and using the curved surface clamp 4 to realize the preliminary clamping and fixing of parts of different sizes;
[0053] After the initial clamping and fixing, the motor 1 501 is started, and the motor 1 501 drives the rotating arm 503 to rotate on the base 1 502. When the rotating arm 503 rotates, the rotating arm 503 pulls the telescopic inner tube 504 rotatably mounted therewith to move, and the telescopic inner tube 504 slides inside the telescopic sleeve 505. Since the telescopic sleeve 505 is rotatably mounted on the base 2 506, when the rotating arm 503 rotates, the telescopic inner tube 504 drives the telescopic sleeve 505 to rotate on the base 2 506. The angle of the curved surface fixture 4 is adjusted by the rotation of the telescopic sleeve 505. After clamping the part, starting the cylinder 1 507 can push the curved surface fixture 4 to apply a force in the direction of the processing base plate 2, so that the part is more stably fixed on the processing base plate 2.
[0054] When processing one side of the part, by starting the motor three 9 on the base 1, the motor three 9 drives the bevel gear one 11 to rotate on the base four 10, the bevel gear one 11 drives the bevel gear two 12 to rotate, and the bevel gear two 12 drives the rotating shaft 15 to rotate on the fixed base 14, thereby realizing the driving of the rotating shaft 15. When the rotating shaft 15 rotates, it is fixedly connected to the rotating shaft 15 through the connecting block 13, so that the connecting block 13 drives the processing base plate 2 to rotate, adjusts the part placement angle, and performs mechanical processing on the side of the part.

Under the driving action of the second cylinder (701), the two support seats (3) are brought close to each other, thereby realizing the driving of the support seats (3), and the curved surface clamp (4) is used to realize the preliminary clamping and fixing of parts of different sizes; After the initial clamping and fixing, the motor 1 (501) is started, and the motor 1 (501) drives the rotating arm (503) to rotate on the base 1 (502). When the rotating arm (503) rotates, the rotating arm (503) pulls the telescopic inner tube (504) rotatably mounted therewith to move, and the telescopic inner tube (504) slides inside the telescopic sleeve (505). Since the telescopic sleeve (505) is rotatably mounted on the base 2 (506), when the rotating arm (503) rotates, the telescopic inner tube (504) drives the telescopic sleeve (505) to rotate on the base 2 (506). The angle of the curved surface clamp (4) is adjusted by the rotation of the telescopic sleeve (505). After the part is clamped, the cylinder 1 (507) is started to push the curved surface clamp (4) to apply a force in the direction of the processing base plate (2), so that the part is more stably fixed on the processing base plate (2); When processing one side of a part, the motor three (9) on the base (1) is started, and the motor three (9) drives the bevel gear one (11) to rotate on the base four (10), and the bevel gear one (11) drives the bevel gear two (12) to rotate, and the bevel gear two (12) drives the rotating shaft (15) to rotate on the fixed base (14), thereby realizing the driving of the rotating shaft (15). When the rotating shaft (15) rotates, the connecting block (13) is fixedly connected to the rotating shaft (15), so that the connecting block (13) drives the processing bottom plate (2) to rotate, adjusts the placement angle of the part, and performs mechanical processing on the side of the part.
