Description

Technical Field

[0001] This utility model relates to the field of automotive drive shaft technology, specifically a placement rack for automotive drive shaft production. Background Technology

[0002] The driveshaft is an important component in the automotive transmission system, connecting the transmission and the drive axle. The basic parameters of the driveshaft are determined by the overall layout design of the vehicle. It must be properly matched with the vehicle to meet the performance requirements of the vehicle. The basic parameters of the driveshaft vary from vehicle model to vehicle model, but their basic structures are similar.

[0003] A search revealed a Chinese patent with publication number CN220741127U that discloses a placement rack for automobile driveshaft production. The key technical point of this patent is that it solves the problem that during the current production and processing of automobile driveshafts, the driveshafts to be processed are sometimes placed directly on the ground or workbench, which easily leads to disorderly placement of the driveshafts, makes it difficult for workers to pick them up, and causes inconvenience to the production of automobile driveshafts.

[0004] However, in the above solution, it was found that each layer of placement board can only be connected to the corresponding slot on the side of the vertical board, resulting in the placement rack being able to hold only three layers of placement boards. Furthermore, the height of the placement boards is fixed, and the number of placement boards cannot be increased or decreased. Consequently, operators cannot make reasonable use of the placement space. In order to solve the problem of the inability to increase or decrease the number of placement boards in the above solution, which prevents operators from making reasonable use of the placement space, this application proposes to set up components such as meshing blocks and limit strips. By raising and lowering the support plate to a specified height, and then connecting the meshing teeth on the surface of the meshing block and the limit strip, the height of the support plate can be adjusted. At the same time, it is convenient to reduce or increase the number of support plates according to actual use, so that operators can make reasonable use of the placement space. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The above-mentioned background technology addresses the shortcomings and defects of existing technologies, such as the inability to increase or decrease the number of placement boards, which prevents operators from making reasonable use of the placement space.

[0006] This utility model discloses a placement rack for automobile driveshaft production, comprising two vertical rods, two support plates, and a movable base plate. Each vertical rod has a limiting groove on its adjacent side. A limiting strip is fixedly connected to the inner wall of each limiting groove. A limiting block is slidably connected to the inner wall of each limiting groove. A connecting rod is rotatably connected to the inner wall of each limiting block. A gear is fixedly connected to the bottom end of each connecting rod. A rack meshes with the outer surface of each gear. A meshing block is fixedly connected to the back of each rack. A worm gear is fixedly connected to the outer surface of each connecting rod. A worm meshes with the outer surface of each worm gear. The left and right sides of each support plate are fixedly connected to the outer surface of the corresponding limiting block.

[0007] Furthermore, a limiting component is fixedly connected to the upper surface of each limiting block, and the inner wall of each limiting component is rotatably connected to the outer surface of the corresponding worm gear.

[0008] Furthermore, a guide rod is fixedly connected to the inner bottom wall of each of the limiting grooves, the outer surface of each guide rod is slidably connected to the inner wall of the corresponding limiting block, and the bottom surface of each vertical rod is fixedly connected to the upper surface of the movable base plate.

[0009] Furthermore, the upper surface of the movable base plate is fixedly connected with round rods arranged at equal intervals, each round rod has a positioning groove on its outer surface, and a positioning block is slidably connected to the inner wall of each positioning groove. The left and right sides of each support plate are fixedly connected to the outer surface of the corresponding positioning block.

[0010] Furthermore, each of the support plates and the movable base plate has a mounting seat fixedly connected to its upper surface at equal intervals, each mounting seat has a sliding groove on its upper surface, and each mounting seat has a clamping member fixedly connected to its upper surface.

[0011] Furthermore, each of the sliding grooves has a sliding block slidably connected to its inner wall, and each of the sliding blocks has a clamping member fixedly connected to its upper surface.

[0012] Furthermore, each of the second clamping members has a threaded handle threadedly connected to its inner wall, and a clamping block is fixedly connected to the bottom end of each threaded handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model incorporates components such as a limiting strip, a limiting block, a gear, a rack, a meshing block, a worm gear, and a worm. Rotating the corresponding worm causes the worm gear to rotate, which in turn causes the gear to rotate. The connection between the gear and the rack allows the meshing block to move. Disconnecting the meshing block from the limiting strip allows the support plate to move, causing the limiting block to slide up and down to the desired position. Reversing the worm allows the meshing block to connect with the meshing teeth on the limiting strip, thus limiting the support plate. Furthermore, the support plate can be disassembled via the limiting groove and the limiting block. This allows for easy adjustment of the support plate height and facilitates the reduction or addition of the number of support plates based on actual usage, enabling operators to make reasonable use of the placement space.

[0015] 2. This utility model, by setting up a mounting base, a sliding block, a second clamping component, a threaded handle, a pressing block, and a first clamping component, places the drive shaft above the corresponding mounting base and places it corresponding to the first and second clamping components. At this time, moving the second clamping component causes the sliding block to move inside the sliding groove until the second and first clamping components clamp the drive shaft. Then, rotating the threaded handle causes the pressing block to descend and connect with the inner bottom wall of the sliding groove, locking the sliding block and thus clamping the drive shaft. Furthermore, by setting the first and second clamping components, drive shafts of different sizes can be clamped. Attached Figure Description

[0025] In this embodiment, a worm gear 9 is fixedly connected to the outer surface of each connecting rod 5. The worm gear 9 is installed on the surface of the connecting rod 5 and set as a fixed connection. The rotation of the worm gear 9 can realize the rotation effect of the connecting rod 5.

The limiting member 12 is connected to the corresponding worm gear 10 and is set as a rotatable connection to achieve the supporting and limiting effect of the worm gear 10.

[0027] Looking back Figure 3 Each limiting groove 2 has a guide rod 13 fixedly connected to its inner bottom wall. The guide rod 13 is installed on the inner bottom wall of the corresponding limiting groove 2 and is set as a fixed connection to achieve the positioning and installation effect of the guide rod 13. The outer surface of each guide rod 13 is slidably connected to the inner wall of the corresponding limiting block 4. The guide rod 13 is connected to the limiting block 4 and is set as a sliding connection. The guide rod 13 is used to achieve secondary limiting of the limiting block 4. The bottom surface of each vertical rod 1 is fixedly connected to the upper surface of the movable base plate 14. The movable base plate 14 is connected to the vertical rod 1 to support the vertical rod 1. The movable base plate 14 is used to facilitate the movement of the entire device.

[0028] In this embodiment, the upper surface of the movable base plate 14 is fixedly connected with equidistantly arranged circular rods 15. The circular rods 15 are installed on the upper surface of the movable base plate 14 to support the circular rods 15. Each circular rod 15 has a positioning groove 16 on its outer surface. The positioning groove 16 is opened on the surface of the circular rod 15 to achieve the positioning effect of the positioning groove 16. The inner wall of each positioning groove 16 is slidably connected with a positioning block 17. The left and right sides of each support plate 11 are fixedly connected to the outer surface of the corresponding positioning block 17. The positioning block 17 is installed on the inner wall of the corresponding positioning groove 16 and is set to a sliding connection. The positioning block 17 is connected to the support plate 11, so that the positioning block 17 can limit the front and rear sides of the support plate 11 and ensure the stability of the support plate 11.

[0029] Combination Figure 1 and Figure 4Each support plate 11 and movable base plate 14 has a fixedly connected mounting base 18 arranged at equal intervals on its upper surface. The mounting base 18 is set on the upper surface of the support plate 11 and movable base plate 14. Each mounting base 18 has a sliding groove 19 on its upper surface. The sliding groove 19 is set on the upper surface of the mounting base 18 to achieve positioning of the sliding groove 19. Each mounting base 18 has a fixedly connected clamping member 24 on its upper surface. The clamping member 24 is installed on the upper surface of the corresponding mounting base 18 to achieve support for the clamping member 24.

[0030] In a preferred embodiment, a sliding block 20 is slidably connected to the inner wall of each sliding groove 19. The sliding block 20 is installed on the inner wall of the corresponding sliding groove 19 and is set as a sliding connection. The contour of the sliding groove 19 can achieve the limiting effect of the sliding block 20. A clamping member 21 is fixedly connected to the upper surface of each sliding block 20. The clamping member 21 is installed on the upper surface of the corresponding sliding block 20 and is set as a fixed connection. The movement of the sliding block 20 can realize the movement of the clamping member 21. By setting the clamping member 21 and the clamping member 24, different sizes of drive shafts can be clamped.

[0031] In this embodiment, each clamping member 21 has a threaded handle 22 threadedly connected to its inner wall. The threaded handle 22 is installed on the inner wall of the corresponding clamping member 21 and is set as a threaded connection. The threaded handle 22 can be raised and lowered by rotating it. Each threaded handle 22 has a pressing block 23 fixedly connected to its bottom end. The pressing block 23 is installed on the bottom end of the threaded handle 22. The pressing block 23 can be connected to the bottom wall of the sliding groove 19 by raising and lowering the threaded handle 22, thereby facilitating the movement and locking of the sliding block 20.

[0032] The implementation principle is as follows: The movable support plate 11 drives the corresponding limiting block 4 to connect with the guide rod 13 and the limiting groove 2. When it moves to the specified height, the worm gear 10 is rotated, causing the worm wheel 9 to rotate. At this time, the worm wheel 9 drives the gear 6 to rotate through the connecting rod 5, which in turn causes the rack 7 to drive the meshing block 8 to connect with the meshing teeth on the surface of the limiting strip 3, locking the support plate 11. This makes it easy to adjust the number and height of the support plates 11, allowing the operator to make reasonable use of the placement space. The drive shaft is placed above the corresponding mounting base 18 and is placed in correspondence with the clamping part 1 24 and the clamping part 21. At this time, the clamping part 21 is moved, causing the sliding block 20 to move inside the sliding groove 19 until the clamping part 21 and the clamping part 1 24 clamp the drive shaft. Then, the threaded handle 22 is rotated, causing the clamping block 23 to descend and connect with the inner bottom wall of the sliding groove 19, locking the sliding block 20 and realizing the clamping of the drive shaft. It can clamp drive shafts of different sizes.
