Description

Technical Field

[0001] This utility model belongs to the field of assembly tool technology, and more specifically, it relates to a manual tool for assembling gearbox housings. Background Technology

[0002] In the production, manufacturing, maintenance and repair of gearboxes, gearbox assembly is a key process, involving multiple operations such as bolt tightening, part positioning, dimensional measurement, and metal shavings removal, which requires a high degree of professionalism and compatibility of tools.

[0003] Current assembly tools still have the following shortcomings:

[0004] In traditional assembly operations, operators need to carry multiple independent tools such as screwdrivers, wrenches, calipers, magnetic rods, and clamps. In actual operation, they often need to frequently switch between different tools, which seriously affects assembly efficiency and is also prone to loss due to the messy stacking of tools. At the same time, the internal structure of the gearbox is compact and the internal space is narrow. The shape design of traditional tools mostly does not take into account the operation requirements of such special spaces. As a result, when removing bolts or installing parts deep inside the gearbox, the tools are difficult to reach, and may even be unable to perform their work due to limited operating space. They may have to rely on additional extension rods and other auxiliary tools, which further increases the complexity and difficulty of the operation. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a manual tool for assembling gearbox housings, thereby resolving the issues raised in the background art, such as the need for frequent switching between different tools during actual operation, which severely impacts assembly efficiency and makes tools prone to loss due to cluttered storage.

[0006] The purpose and function of this utility model, a manual tool for assembling a gearbox housing, are achieved by the following specific technical means:

[0007] A manual tool for assembling a gearbox housing includes: a left handle; the left handle has a cylindrical structure and a screw hole on one side; a right handle with a cylindrical structure is threadedly installed on one side of the left handle; a set of mountain-shaped mounting plates are fixedly installed on the outer ends of both the left and right handles, and the outer ends of the mounting plates have through-hole circular slots; a set of circular plate-shaped connecting blocks are rotatably installed on the upper and lower sides of one end of the inner side of both sets of mounting plates, and a Phillips head screwdriver, a flathead screwdriver, an Allen wrench, and a magnetic rod are arranged in a circular array on the outer side of the connecting blocks on the upper left side.

[0008] Furthermore, a first side rod with a semi-circular rod structure is fixedly provided on both sides of the left handle; a set of second side rods with a semi-circular rod structure is fixedly provided on both sides of the right handle, and the first side rods and the second side rods are combined to form a cylindrical rod structure.

[0009] Furthermore, a cylindrical connecting shaft is provided on the outer side of the connecting block. The connecting shaft passes through a circular through groove on the mounting plate, and a cross-shaped groove structure is provided on the outer end of the connecting shaft.

[0010] Furthermore, a set of U-shaped plate structure limiting plates are fixedly installed on the upper and lower sides of the outer side of the mounting plate, and a through rectangular groove structure is opened on the top of the limiting plate; a rectangular rod structure sliding rod is slidably installed in the rectangular groove of the limiting plate, and a spring is sleeved on the outside of the sliding rod; a cross-shaped block structure locking block is fixedly installed at the bottom end of the sliding rod.

[0011] Furthermore, a caliper is fixedly connected to one side of the upper right group of connecting blocks; a multi-functional plate is fixedly connected to one side of the lower right group of connecting blocks, and a socket wrench and a box wrench are provided on the multi-functional plate.

[0012] Furthermore, a rectangular plate structure fixing plate is fixedly installed on one side of the lower left group of connecting blocks, and a T-shaped groove structure is opened at one end of the fixing plate. A set of wedge-shaped clamping blocks is fixedly installed on one side of the fixing plate; a lead screw is rotatably installed in the T-shaped groove on one side of the fixing plate; a set of wedge-shaped clamping blocks is slidably installed in the T-shaped groove of the fixing plate, and this set of clamping blocks is connected to the lead screw through threaded engagement.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This tool integrates multiple functions, including a Phillips head screwdriver, a flathead screwdriver, an Allen wrench, a magnetic rod, calipers, a socket wrench, a box wrench, and a clamping mechanism. Operators no longer need to frequently switch between multiple separate tools. They can quickly switch between the required functions through simple rotation and locking operations according to the assembly steps. For example, after tightening the bolts, there is no need to find the calipers separately. Simply rotate the connecting block to bring up the calipers for measurement. After measurement, the tool can be quickly switched to the magnetic rod to clean up iron filings. This significantly reduces the time spent picking up and changing tools, and greatly improves the continuity and efficiency of assembly operations.

[0015] The tool adopts a modular rotating design, and each functional module can be rotated 360° through the connecting block. It can flexibly adapt to the narrow and complex space environment inside the gearbox. When it is necessary to operate on the bolts deep inside the gearbox, the multi-functional plate can be rotated to adjust the socket wrench or box wrench to the appropriate angle, and easily reach into the gearbox to complete the tightening or disassembly operation. This effectively solves the problem that traditional tools are difficult to operate in narrow spaces.

[0016] The left and right handles are connected by a threaded connection, allowing for flexible separation or combination according to actual usage needs. In the combined state, the first and second side rods form a complete cylindrical grip, with an anti-slip design, making it easy for the operator to apply rotational force. In the separated state, it can adapt to different working environments, especially in situations with extremely limited space, where single-handle operation is more flexible.

Alternatively, the right handle 102 and left handle 1 can be separated for operation as needed, facilitating adjustments for different usage environments. Once assembled, they are easier to carry and store. To use any function, pull the set of sliding rods 108 above the corresponding set of connecting blocks 105, causing the locking block 109 to completely disengage from the groove of the connecting shaft 106. Then, the corresponding set of connecting blocks 105 can be rotated according to the desired function. If a screwdriver or similar function is needed, rotate the connecting block 105 clockwise or counterclockwise to insert the required screwdriver tip (Phillips head). Align the flathead / hexagonal wrench or magnetic rod with the working direction, then release the slide bar 108. The spring pushes the locking block 109 into the corresponding groove, locking the connecting block 105. At this time, you can hold the left handle 1 or the right handle 102 to perform the corresponding operation. When using a socket wrench or box wrench, rotate the multi-function plate 111 out in the same way. When using calipers 110, rotate the connecting block 105 of the caliper 110 set out in the same way. When using an adjustable wrench, rotate the fixed plate 112 to the outside of the mounting plate 104. Rotate the screw 113 to drive one set of clamping blocks 114 to slide along the T-shaped groove on the outside of the fixed plate 112. Adjust the distance between the two sets of clamping blocks 114 to meet the clamping requirements, and then it can be used.

[0033] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown:

[0034] The left handle 1 has a first side rod 101 with a semi-circular rod structure fixed on both sides; the right handle 102 has a second side rod 103 with a semi-circular rod structure fixed on both sides, and the first side rod 101 and the second side rod 103 are combined to form a cylindrical rod structure.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, during rotational operation, the two sets of first side rods 101 and second side rods 103 work together to make it easier to grip and apply rotational force, thus facilitating operation.
