Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining equipment technology, specifically a support bracket for shaft machining. Background Technology
[0002] In the machining of shaft parts, support brackets are one of the key pieces of equipment to ensure machining accuracy and stability. Shaft parts are usually quite long and have a large diameter. If there is a lack of effective support during machining, they are prone to bending and deformation due to their own weight, resulting in dimensional errors and shape deviations in the machined shaft parts, which seriously affects product quality.
[0003] Based on the above, the inventors have discovered the following problems: current shaft machining support brackets mostly adopt fixed support structures, and their support height and position are difficult to adjust flexibly according to the machining requirements of shaft parts of different specifications.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a support bracket for shaft machining in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this utility model is to provide a support bracket for shaft processing, so as to solve the problem mentioned in the background art that the current support brackets for shaft processing mostly adopt a fixed support structure when in use, and it is difficult to flexibly adjust the support height and support position according to the processing requirements of shaft parts of different specifications.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A support bracket for shaft machining includes a base plate, a lifting plate mounted on the top of the base plate, a height adjustment mechanism for adjusting the height of the lifting plate on the top of the base plate, a frame mounted on the top of the lifting plate, slide rails mounted on both sides of the top of the frame, sliding sleeves slidably connected to both sides of the top of the slide rails, a retainer mounted on the top of a pair of slide sleeves, a rotating shaft rotatably connected to the inner side of the retainer, a bearing roller fitted on the outer side of the rotating shaft, a positioning mechanism for limiting the rotation of the rotating shaft mounted on one side of the retainer, and a distance adjustment mechanism for adjusting the distance between the pair of retainers inside the frame.
[0007] Furthermore, the height adjustment mechanism includes a first bidirectional threaded rod, with a first slider fitted at both ends of the first bidirectional threaded rod. A first support rod is hinged to the top of the first slider, and the top of the first support rod is hinged to the bottom of the lifting plate. A second support rod is hinged to the bottom of the first slider, and the bottom of the second support rod is hinged to the top of the base plate. A crank handle is installed at one end of the first bidirectional threaded rod.
[0008] The beneficial effect of adopting the above-mentioned further solution is that by adjusting the first bidirectional threaded rod, the first slider, and the support rod assembly of the height adjustment mechanism, the crank can rotate the first bidirectional threaded rod, drive the first slider to move, and cause the first support rod and the second support rod to unfold or retract, thereby realizing the height adjustment of the lifting plate.
[0009] Furthermore, the adjusting mechanism includes a second bidirectional threaded rod, the two ends of which are rotatably connected to the inner end faces of the frame, and a second slider is fitted on both ends of the second bidirectional threaded rod. The top ends of a pair of second sliders are respectively fixedly connected to the bottom ends of a pair of retainers.
[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the second bidirectional threaded rod and the second slider of the adjusting mechanism, the rotation of the second bidirectional threaded rod drives the second sliders on both sides to move synchronously in opposite directions, thereby accurately adjusting the distance between a pair of cages and bearing rollers, and adapting to the support requirements of shafts with different diameters.
[0011] Furthermore, one end of the frame is provided with a first adjustment knob, and one end of the first adjustment knob is connected to one end of the second bidirectional threaded rod.
[0012] The beneficial effect of adopting the above-mentioned further solution is that, through the first adjustment knob on one end face of the frame, the second bidirectional threaded rod can be easily rotated manually, and the operator can intuitively control the spacing of the bearing rollers.
[0013] Furthermore, the positioning mechanism includes a side frame, a one-way threaded rod is installed on the inner side of the side frame, a connecting seat is rotatably connected to the top of the one-way threaded rod, an insert block is installed on the top of the connecting seat, a chuck is installed at one end of the rotating shaft, and a plurality of slots are opened on the outer side of the chuck, the inner side of the slots and the outer side of the insert block are engaged and connected.
[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the one-way threaded rod, insert block, and chuck of the positioning mechanism, the one-way threaded rod pushes the connecting seat and insert block into the chuck slot, locking the rotation of the rotating shaft and the bearing roller, preventing the shaft from rotating due to friction during machining, ensuring accurate positioning of the shaft, and improving machining accuracy.
[0015] Furthermore, a second adjustment knob is installed at the bottom end of the one-way threaded rod.
[0016] The beneficial effect of adopting the above-mentioned further solution is that, through the second adjustment knob at the bottom of the one-way threaded rod, the second adjustment knob can be used to manually control the lifting and lowering of the insert block, and quickly achieve the locking and unlocking of the bearing roller.
[0017] Furthermore, a pair of fixing seats are installed on both sides of the base plate.
[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the fixing seats on both sides of the base plate, the fixing seats can be fixed to the ground or processing table with bolts, which enhances the overall stability and prevents the bracket from shifting due to force during shaft processing.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The support bracket for shaft processing provides a stable foundation through the base plate; the height adjustment mechanism adjusts the height of the lifting plate to adapt to the processing needs of different shaft types; the slide rail and slide sleeve cooperate to ensure smooth movement of the retainer; the distance adjustment mechanism adjusts the spacing of the bearing rollers to adapt to shafts of different diameters; the positioning mechanism fixes the rotating shaft and bearing rollers to prevent rotational deviation during shaft processing; through the first bidirectional threaded rod, first slider, and support rod assembly of the height adjustment mechanism, the crank handle rotates the first bidirectional threaded rod, driving the first slider to move, causing the first and second support rods to unfold or retract, thereby achieving height adjustment of the lifting plate; through the second bidirectional threaded rod and second slider of the distance adjustment mechanism, the rotation of the second bidirectional threaded rod drives the second sliders on both sides to move synchronously in opposite directions, precisely adjusting the spacing of a pair of retainers and bearing rollers to adapt to the support needs of shafts of different diameters. The first adjustment knob on one end face of the bracket allows for easy manual rotation of the second bidirectional threaded rod, enabling the operator to intuitively control the spacing of the bearing rollers. Through the unidirectional threaded rod, insert block, and chuck of the positioning mechanism, the unidirectional threaded rod pushes the connecting seat and insert block into the chuck's groove, locking the rotating shaft and bearing rollers to prevent rotation due to friction during shaft processing, ensuring accurate shaft positioning and improving processing precision. The second adjustment knob at the bottom of the unidirectional threaded rod allows for easy manual control of the insert block's raising and lowering, quickly locking and unlocking the bearing rollers. The fixed seats on both sides of the base plate allow the bracket to be fixed to the ground or processing table with bolts, enhancing overall stability and preventing displacement of the bracket due to force during shaft processing. This invention effectively integrates shaft support, height adjustment, spacing adaptation, and positioning, improving processing stability and possessing high practical value.
