Description

Technical Field

[0001] This utility model relates to the technical field of slender shaft machining, and in particular to an anti-deformation support device for slender shaft machining. Background Technology

[0002] In the field of machining, slender shafts are prone to deformation during machining due to their structural characteristics. Therefore, a deformation-preventing support device is needed for machining slender shafts.

[0003] Slender shafts have poor rigidity and are prone to bending deformation under the action of cutting force, gravity and centrifugal force, which leads to a decrease in machining accuracy. Traditional support devices are mostly fixed structures and are often bulky, occupying a lot of workshop space when not in operation, which is not conducive to production site management.

[0004] To address the aforementioned problems, a deformation-resistant support device for machining slender shafts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-deformation support device for machining slender shafts, so as to solve the problem of the existing anti-deformation support devices for machining slender shafts mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant support device for machining slender shafts, comprising a main frame, side storage racks, side unfolding racks, storage grooves, sliding grooves, a central support block, a positioning groove, a placement groove, a shaft column, side support blocks, positioning blocks, and rubber strips. Side storage racks are fixedly arranged on both sides of the main frame, and side unfolding racks are arranged inside the side storage racks. Storage grooves for storing the side unfolding racks are opened on the side storage racks, and sliding grooves that cooperate with the shaft column are opened at both ends of the side storage racks. The side unfolding racks are rotatably connected to the side storage racks through the shaft column. A central support block is installed on the top of the main frame, a side support block is provided on the top side of the side unfolding frame, and a positioning groove and a placement groove are provided on the side unfolding frame. The adhesive strip is fixedly installed on the outer surface of the positioning block.

[0007] Preferably, the side unfolding frame rotates 90 degrees around the axis column to achieve complete storage in the storage slot.

[0008] Preferably, when the side unfolding frame is stored in the storage slot, the positioning block is elastically engaged into the placement slot by an adhesive strip.

[0009] Preferably, the side support blocks are symmetrically arranged on both sides of the central support block, and the height of the central support block is the same as the height of the side support blocks.

[0010] Preferably, the shaft is slidably connected to the groove.

[0011] Preferably, the side support block is installed on one side of the positioning groove, and the side support block is rotatably connected to the side unfolding frame. When the side unfolding frame is fully unfolded, the side support block can be embedded in the positioning groove to form a positioning.

[0012] Preferably, the rubber strip is made of elastic rubber material to enhance the friction and buffering effect between the positioning block and the placement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The three-point support structure formed by the central support block and the two side support blocks can evenly distribute the gravity load of the slender shaft and reduce bending deformation caused by insufficient rigidity. 2. The side-expanding frame structure can adapt to the processing needs of slender shafts of different lengths. Depending on the length of the slender shaft, two-point support or three-point support can be selected by unfolding the side-expanding frame on both sides at the same time, which can better reduce the space occupation rate. 3. Through the sliding fit between the shaft column and the slide groove, the side unfolding frame can be rotated and unfolded and stored at ninety degrees. The side unfolding frame and the side support block can be completely stored in the storage slot of the side storage frame, which greatly reduces the space occupation in the non-working state and is conducive to the rational use of workshop space.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figure 1-3As shown, the device includes a main frame 1, a side storage rack 2, a side unfolding rack 3, a storage slot 4, a sliding groove 5, a central support block 6, a positioning slot 7, a placement slot 8, a shaft column 9, a side support block 10, a positioning block 11, and an adhesive strip 12. The side storage rack 2 is fixedly installed on both sides of the main frame 1, and the side unfolding rack 3 is installed on one side of the side storage rack 2. The side storage rack 2 has a storage slot 4 for storing the side unfolding rack 3, and the two ends of the side storage rack 2 have sliding grooves 5 that cooperate with the shaft column 9. The side unfolding rack 3 is rotatably connected to the side storage rack 2 through the shaft column 9.

[0018] It should be noted that in this embodiment, the main frame 1, as the basic load-bearing structure of the device, is made of high-strength alloy steel to ensure the overall structural stability. Side storage racks 2 are fixedly installed on both sides of the main frame 1. Side unfolding racks 3 are installed inside the side storage racks 2. Storage grooves 4, matching the shape of the side unfolding racks 3, are provided on the side storage racks 2 for storing the side unfolding racks 3 when not in use. Sliding grooves 5 are provided at both ends of the side storage racks 2. The sliding grooves 5 cooperate with the shafts 9 on the side unfolding racks 3. The side unfolding racks 3 are rotatably connected to the side storage racks 2 via the shafts 9. 9 can slide along the slide groove 5, allowing the side unfolding frame 3 to rotate 90 degrees around the axis column 9, thereby achieving complete storage in the storage slot 4 or unfolding from the storage slot 4. A central support block 6 is installed on the top of the main frame 1 by screws. The top of the central support block 6 is provided with an arc-shaped groove for supporting the middle position of the slender shaft. A side support block 10 is provided on the top side of the side unfolding frame 3. The side support block 10 is also provided with an arc-shaped groove and is symmetrically arranged on both sides of the central support block 6. The height of the central support block 6 is the same as the height of the side support block 10 to ensure that the slender shaft remains horizontal when placed.

[0019] like Figure 4 , 5 As shown, a central support block 6 is installed on the top of the main frame 1, a side support block 10 is provided on the top side of the side unfolding frame 3, and a positioning groove 7 and a placement groove 8 are provided on the side unfolding frame 3. The adhesive strip 12 is fixedly installed on the outer surface of the positioning block 11.

[0020] It should be noted that in this embodiment, the side unfolding frame 3 is also provided with a positioning groove 7 and a placement groove 8. The side support block 10 is installed on one side of the positioning groove 7 and is rotatably connected to the side unfolding frame 3. When the side unfolding frame 3 is fully unfolded, the side support block 10 can be rotated to make it perpendicular to the side unfolding frame 3, and the positioning block 11 is embedded in the positioning groove 7 to limit the side support block 10. The rubber strip 12 is made of elastic rubber material and is fixedly set on the outer surface of the positioning block 11 to enhance the friction and buffering effect between the positioning block 11 and the placement groove 8 and the positioning groove 7. When the side unfolding frame 3 is stored in the storage groove 4, the positioning block 11 is removed and inserted into the placement groove 8, and the side support block 10 is rotated to be placed flat in the positioning groove 7. The side unfolding frame 3 is rotated around the shaft 9 until it is directly above the storage groove 4 in the side storage frame 2. At this time, the shaft 9 slides along the slide groove 5, and the side unfolding frame 3 is stored in the storage groove 4 along the sliding direction of the shaft 9 to realize the storage of the side unfolding frame 3.

[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 The unfolding process is as follows: When it is necessary to process and support the slender shaft, the operator manually pulls the side unfolding frame 3 outward from the storage slot 4. The side unfolding frame 3 rotates around the shaft column 9, and at the same time, the shaft column 9 slides along the slide groove 5. During the rotation, the side support block 10 moves together with the side unfolding frame 3. When the side unfolding frame 3 is fully unfolded, the side support block 10 is rotated to make it perpendicular to the side unfolding frame 3, and the positioning block 11 is taken out from the placement slot 8 and embedded in the positioning slot 7 to limit the side support block 10. At this time, the side support block 10 and the central support block 6 together form a support structure for the slender shaft. Support function: The slender shaft is placed in the arc-shaped grooves of the central support block 6 and the side support block 10. Since the central support block 6 and the side support block 10 are at the same height, the slender shaft can maintain a horizontal state. At the same time, the setting of multiple support points distributes the weight of the slender shaft and reduces the bending deformation of the slender shaft caused by its own gravity. Storage process: After processing is completed, remove the slender shaft from the support device, first remove the positioning block 11 from the positioning groove 7, release the limit of the opposite side support block 10, rotate the side support block 10 to a flat position, so that it is completely stored in the positioning groove 7 of the side unfolding frame 3, reduce the overall thickness to adapt to the storage space, and re-insert the positioning block 11 into the placement groove 8. At this time, push the side unfolding frame 3 so that it rotates around the shaft column 9 towards the storage groove 4. The shaft column 9 slides in the opposite direction along the slide groove 5. When the side unfolding frame 3 rotates to the top of the storage groove 4 of the side storage frame 2, push it completely into the storage groove 4 along the sliding direction of the shaft column 9.
