Description

Technical Field

[0001] This utility model relates to the field of gearbox manufacturing technology, and in particular to a gearbox housing gripper. Background Technology

[0002] Gearbox manufacturing is a core component of automobile and mechanical equipment manufacturing, referring to the assembly of various components into a transmission device with gear-changing capabilities through precision processes. The process encompasses steps such as raw material processing, heat treatment, precision machining, component assembly and performance testing, and gearbox assembly.

[0003] During the gearbox assembly process, workers must precisely assemble the core components into the lower housing according to the process sequence: First, the gear set is positioned on the shaft according to the designed meshing relationship. Then, the bearings are installed and pressed into the bearing holes in the lower housing, while simultaneously checking the gear backlash and axial movement. After the internal components of the lower housing are pre-assembled and tested, the operator aligns the upper housing with the lower housing and fastens them together. A rubber hammer is used to gently tap evenly along the housing mating surface, using micro-vibration to eliminate the fit clearance and ensure that the sealing surfaces of the upper and lower housings and the locating pins of the internal components are fully fitted. Finally, a torque wrench is used to tighten the connecting bolts in a diagonal sequence, while simultaneously checking the housing clearance and oil seal condition, completing the gearbox assembly.

[0004] The shortcomings of the aforementioned existing technical solutions are as follows: In the assembly of gearboxes, the upper and lower metal housings are quite heavy (often exceeding 10 kg per piece), requiring workers to frequently bend over, move, and flip them to complete the fastening operation. Long-term work can easily lead to lumbar muscle strain and other diseases. In addition, after the upper and lower housings are fastened, they need to be tapped point by point with a rubber hammer or by hand to eliminate the fitting gap with slight vibration, resulting in low overall efficiency.

[0006] A gearbox housing gripper includes a lifting assembly. The output end of the lifting assembly is provided with a lifting plate. A front clamping plate is fixedly provided on the front side of the lifting plate. A rear clamping plate that cooperates with the front clamping plate is movably connected to the rear end of the lifting plate. A clamping mechanism is provided on the lifting plate to drive the bottom of the rear clamping plate to move closer to the front clamping plate to clamp the gearbox housing. A vertical vibration motor for generating vertical vibration is fixedly provided above the front clamping plate.

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figures 1 to 4As shown in the figure, this utility model provides a gearbox housing gripper, including a lifting assembly 1. A lifting plate 3 is provided at the output end of the lifting assembly 1. A front clamping plate 5 is fixedly provided on the front side of the lifting plate 3. A rear clamping plate 4, which cooperates with the front clamping plate 5, is movably connected to the rear end of the lifting plate 3. A clamping mechanism 6 is provided on the lifting plate 3 to drive the bottom of the rear clamping plate 4 towards the front clamping plate 5 to clamp the gearbox housing. The operator adjusts the distance between the front clamping plate 5 and the rear clamping plate 4 to clamp the gearbox housing. Then, the lifting assembly 1 on the assembly fixture is used to lift and transport the housing, completing the assembly operation. A vertical vibration motor 2 is fixedly provided above the front clamping plate 5 to generate vertical vibration. During assembly, the vertical vibration motor 2 is turned on to eliminate gaps in the housing fit with slight vibration, improving assembly efficiency.

[0027] In one specific embodiment, the clamping mechanism 6 includes a hinge 604 fixedly mounted on the front side of the lifting plate 3, a clamping lever 603 movably hinged to the hinge 604, a pull rod 601 movably connected to the rear clamping plate 4, the pull rod 601 being movably hinged to the clamping lever 603, and a gripping rod 606 fixedly mounted above the front side of the lifting plate 3, corresponding to the position of the clamping lever 603, for easy gripping and locking of the upper end of the clamping lever 603 by the operator. A through-hole 602 is provided on the front clamping plate 5, through which the pull rod 601 passes and is movably hinged to the clamping lever 603. A bent portion 605 is provided at the upper end of the clamping lever 603, cooperating with the gripping rod 606 for easy gripping by the operator. During use, the operator adjusts the position of the lifting plate 3 so that the gearbox housing is positioned between the rear clamping plate 4 and the front clamping plate 5. Then, the operator pushes the bending part 605 closer to the gripping rod 606 and manually locks the bending part 605 and the gripping rod 606 together, ensuring the entire assembly is in place. Figure 1 As shown, the clamping lever 603 pries the pull rod 601, causing the pull rod 601 to move the rear clamping plate 4 closer to the front clamping plate 5, thereby clamping the gearbox housing.

[0028] like Figure 4 As shown, in this example, the pull rod 601 is hinged to the end of the clamping lever 603 away from the bend 605, and the hinge 604 is movably connected to the lower middle position of the clamping lever 603. This utilizes the lever principle to efficiently and effortlessly drag the rear clamping plate 4, ensuring a secure clamping grip.

[0029] Furthermore, at least one set of first mating blocks 401 for pressing the gearbox housing are fixedly provided on the rear clamping plate 4. The surface shape of each set of first mating blocks 401 on the side close to the gearbox housing is adapted to the shape of the gearbox housing surface. At least one set of second mating blocks 501 for pressing the gearbox housing are fixedly provided on the front clamping plate 5. The surface shape of each set of second mating blocks 501 on the side close to the gearbox housing is adapted to the shape of the gearbox housing surface. The first mating blocks 401 and the second mating blocks 501 are preferably made of rubber, thereby ensuring that the contact surface has a large friction force, improving the clamping firmness, and avoiding damage to the surface of the gearbox housing.

[0030] In one specific embodiment, the lifting assembly 1 includes a slide rail 101 suspended on the assembly fixture. A sliding sleeve 102 is slidably disposed on the slide rail 101. An electric winch 103 is fixedly disposed at the bottom of the sliding sleeve 102. A tightening member 104 is fixedly connected to the end of the twisted cable output by the electric winch 103. The electric winch 103 can control the twisted cable to lift the tightening member 104. A sling 105 is connected between the tightening member 104 and the lifting plate 3. The lifting and lowering of the tightening member 104 will drive the lifting and lowering of the lifting plate 3, thereby driving the lifting and lowering of the clamped gearbox housing, so as to facilitate the transportation of the gearbox housing to the assembly line.

[0031] In this embodiment, the sliding sleeve 102 is rotatably equipped with a rotating wheel that cooperates with the slide rail 101. The rotating wheel reduces the friction between the slide rail 101 and the sliding sleeve 102, allowing the operator to easily push the sliding sleeve 102 to the assembly line while holding the lifting plate 3, and complete the assembly.

[0032] Working Principle: During the gripping phase, the operator first adjusts the position of the lifting plate 3 so that the gearbox housing is positioned between the rear clamping plate 4 and the front clamping plate 5. Then, the operator pushes the bent portion 605 at the upper end of the clamping lever 603, bringing it close to the gripping rod 606, and locks both in place by hand. Based on the lever principle, the clamping lever 603 then pries the pull rod 601, which in turn moves the bottom of the rear clamping plate 4 towards the front clamping plate 5. The first mating block 401 on the rear clamping plate 4 and the second mating block 501 on the front clamping plate 5 work together to tightly compress the gearbox housing, achieving stable clamping. The first mating block 401 and the second mating block 501 are made of rubber, ensuring high friction on the contact surface, improving clamping stability, and preventing damage to the housing surface.

[0033] During the handling phase, the electric winch 103 is fixed to the bottom of the sliding sleeve 102, and the end of its output winch cable is connected to the tightening member 104. The tightening member 104 is connected to the lifting plate 3 via the sling 105. The electric winch 103 controls the winch cable to lift the tightening member 104, thereby driving the lifting plate 3 and the gearbox housing clamped on it to rise and fall. Workers can easily push the sliding sleeve 102 to move and transport the gearbox housing to the assembly line. During assembly, the vertical vibration motor 2 is turned on to generate slight vibrations in the up and down direction, eliminating the housing fitting gaps and improving assembly efficiency.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
