Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shaft part supporting tooling, in particular to a shaft part rotating supporting device. Background Art
[0002] During the processing or transfer of shaft parts such as round tubes or round rods, existing tooling usually uses V-blocks to support them to a limited position. However, friction between this support structure and the parts easily causes wear of the parts. In order to reduce the wear of the parts, rollers are also set on the inner wall of the V-block to form rolling contact with the parts. However, the outer diameter size range of shaft parts that can be adapted by the V-block of this structure is limited, and it can only support shaft parts within a certain diameter range, and its practicality is still poor. Utility Model Content
[0003] In order to solve the deficiencies in the prior art, the utility model provides a rotating support device for shaft parts, which can not only effectively reduce the wear on the parts, but also be suitable for supporting shaft parts with a larger diameter range.
[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:
[0005] A rotating support device for shaft parts comprises: a horizontally arranged support plate, a pair of support seats are arranged on the top surface of the support plate, the support seats are movably arranged along the length direction of the support plate, rollers with axes parallel to each other are arranged on the top surfaces of the support seats, a screw rod is arranged parallel to the top surface of the support plate, and the threads at both ends have opposite rotation directions, the two ends of the screw rod pass through two support seats respectively, and the screw rod is located below the rollers, a support member is arranged in the middle position of the two support seats, which comprises a connecting rod that passes vertically through the support plate, a cylindrical spring is sleeved on the outside of the connecting rod, a pair of pulleys parallel to each other are arranged on the top of the connecting rod, and the axes are parallel to the rollers, the cylindrical spring is located between the support plate and the pulley, and when the cylindrical spring is in a natural state, the top surface of the pulley is higher than the contact part between the roller and the shaft part.
[0006] The beneficial effects of the utility model are: the distance between the two rollers can be adjusted by rotating the screw rod, so as to adapt to shaft parts with a larger diameter range; and the support member can be used to effectively buffer the impact force when placing the parts, avoiding damage to the support device. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present invention.
[0008] Figure 1 Shown is a schematic diagram of the overall structure of the present application.
[0009] Markings in the figure: support plate-1, support seat-2, roller-21, block-22, screw-3, disc-31, support member-4, cylindrical spring-41, pulley-42, lifting device-5, mobile platform-6, connecting hole-61. DETAILED DESCRIPTION
[0010] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0011] like Figure 1 As shown, a rotating support device for shaft parts comprises: a horizontally arranged support plate 1, a pair of support seats 2 are arranged on the top surface of which, the support seats 2 are movably arranged along the length direction of the support plate 1, and rollers 21 with parallel axes are arranged on the top surfaces of the support seats 2. A screw rod 3 is arranged in parallel on the top surface of the support plate 1, and the threads at both ends thereof are rotated in opposite directions. The two ends of the screw rod 3 pass through the two support seats 2 respectively, and the screw rod 3 is located below the rollers 21 to prevent the shaft parts from bending the screw rod 3. By rotating the screw 3, the two support seats 2 can be driven to move synchronously in relative or opposite directions along the length direction of the screw rod 3 to adjust the distance between the two rollers 21, so as to adapt to shaft parts with a larger diameter range. A support member 4 is arranged in the middle position of the two support seats 2, which comprises a connecting rod vertically passing through the support plate 1, and a cylindrical spring is sleeved on the outside of the connecting rod 41. A pair of pulleys 42 are parallel to each other at the top of the connecting rod, and their axes are parallel to the roller 21. The cylindrical spring 41 is located between the support plate 1 and the pulley 42. When the cylindrical spring 41 is in a natural state, the top surface of the pulley 42 is higher than the contact position between the roller 21 and the shaft parts. In this way, when the shaft parts are lowered into the supporting device, the cylindrical spring 41 of the support member 4 can be used to buffer them, so as to avoid the shaft parts from impacting the screw 3 through the roller 21 and the support seat 2, thereby preventing the thread of the screw 3 from being deformed, and also preventing the shaft parts from falling on the screw 3 when the distance between the two support seats 2 is adjusted too large, causing the screw 3 to be deformed. When the shaft parts are in contact with the roller 21 and rotate, the support member 4 can roll with the shaft parts through the pulley 42 to avoid wear on the shaft parts.
[0012] Preferably, Figure 1 As shown, the support seat 2 has a stopper 22 extending upward on one side facing the end of the support plate 1. The stopper 22 is located outside the roller 21 and is higher than the roller 21 to prevent shaft parts from falling.
[0013] Preferably, Figure 1 As shown, discs 31 are provided at both ends of the screw rod 3 for manual rotation.
[0014] Preferably, Figure 1 As shown, the support plate 1 is arranged at the top end of a movable rod of a lifting device 5 so that the height position of the support plate 1 can be controlled by using the lifting device 5 .
[0015] Preferably, Figure 1 As shown, the lifting device 5 is arranged on the top of a mobile platform 6, and the bottom of the mobile platform 6 is provided with moving wheels around to facilitate transfer.
[0016] Preferably, Figure 1 As shown, the peripheral side of the mobile platform 6 is provided with connection holes 61 for passing rods. By passing the rods through the connection holes 61, multiple mobile platforms 6 can be connected to facilitate the overall transfer of shaft parts.
[0017] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
