Description

Technical Field

[0001] This utility model relates to the technical field of excavator cab glass processing equipment, specifically an excavator cab glass inspection tool. Background Technology

[0002] An excavator is a self-propelled power unit used to tow and drive construction machinery to complete various mobile tasks, and can also be used for stationary work. It consists of an engine, transmission, travel system, steering system, hydraulic suspension, power output, electrical instruments, driving controls, and towing systems or devices. The cab is an important component of the body of trucks and special-purpose vehicles, and is where professional drivers work day and night. Its structure directly affects the driver's safety, work efficiency, and health. The cab generally adopts a thin-shell metal structure, flexibly connected to the frame, and does not bear loads; it is a non-load-bearing body.

[0003] Excavator cab glass inspection fixture is a tooling used to inspect the glass of an excavator cab. Before inspection, it is usually necessary to use a fixing device to fix the glass. For example, Chinese utility model patent with announcement number CN216646518U specifically discloses an excavator cab glass inspection fixture.

[0004] However, in actual use, it has been found that the spacing of the locking blocks of the aforementioned excavator cab inspection tool is fixed, which makes it difficult to clamp and fix glass of different specifications, resulting in poor applicability. Utility Model Content

[0005] The purpose of this utility model is to provide a glass inspection tool for excavator cabs, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glass inspection tool for an excavator cab, comprising a worktable, a lifting and adjusting assembly, a first clamping assembly, and a second clamping assembly.

[0007] The lifting adjustment component is located above the worktable and is used to adjust the height and angle of the first clamping component and the second clamping component. The first clamping component is located above the lifting adjustment component, and the second clamping component is located on the first clamping component. The first clamping component and the second clamping component are used to clamp and fix the excavator cab glass.

[0008] In a preferred embodiment of this invention, the lifting and adjusting assembly includes a first lifting push rod, a first connecting seat, a second lifting push rod, a second connecting seat, and a first drive motor. The first and second lifting push rods are fixed inside the worktable. The first connecting seat is fixed to the top of the first lifting push rod, and the second connecting seat is fixed to the top of the second lifting push rod. A first clamping assembly is disposed between the first and second connecting seats. The first drive motor is fixed to the outside of the first connecting seat. By pushing the first and second lifting push rods, the first and second connecting seats are simultaneously raised and lowered. The first and second connecting seats drive the first and second clamping assemblies to rise and fall. Furthermore, the first drive motor drives the first clamping assembly to rotate, thereby adjusting the angle of the first and second clamping assemblies.

[0009] In a preferred embodiment of this invention, the first clamping assembly includes a first slide rail, a lead screw, a first slider, a second drive motor, a second slide rail, a second slider, a first connecting plate, and a first clamping block. The first slide rail is rotatably connected to a first connecting seat, and the second slide rail is rotatably connected to a second connecting seat. The drive shaft of the first drive motor is connected to the first slide rail. The lead screw is rotatably connected to the inner side of the first slide rail, and two symmetrical first sliders are threaded onto the lead screw. The second drive motor is fixed to the end of the first slide rail, and its drive shaft is connected to the lead screw. Two symmetrical second sliders are symmetrically slidably connected within the second slide rail. The first and second sliders are aligned with each other, and a first connecting plate is fixed between the aligned first and second sliders. A first clamping block is fixed to the first connecting plate. The first drive motor drives the first slide rail to rotate, and because the first and second slide rails are interconnected, the entire first clamping assembly rotates, thereby changing its angle. The second drive motor drives the lead screw to rotate, which in turn drives the two first sliders to move closer or further apart. This causes the first slider to move the second slider via the first connecting plate, improving the stability of the movement. The first clamping block on the first connecting plate clamps one or both sides of the glass.

[0010] As a preferred embodiment of this invention, a support rod is fixed between the first slide rail and the second slide rail. This improves the synchronization stability between the first slide rail and the second slide rail.

[0011] In a preferred embodiment of this invention, the second clamping assembly includes a mounting plate, a clamping push rod, a second connecting plate, and a second clamping block. Mounting plates are disposed above both the first and second slide rails. A clamping push rod is fixed above each clamping plate. The second connecting plate is fixed to the end of the clamping push rod, and the second clamping block is fixed to the second connecting plate. By moving the second connecting plate with the clamping push rod, the second clamping block on the second connecting plate clamps the other two sides of the excavator cab glass, improving the clamping effect.

[0012] As a preferred embodiment of the present invention, the first slide rail and the mounting plate, and the second slide rail and the mounting plate are both fixed by bolts, thereby facilitating the separation of the second clamping assembly from the first clamping assembly.

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

[0014] This invention, through the first clamping component and the second clamping component, can adapt to the requirements of glass position under different specifications and different testing scenarios, thereby improving the versatility of the inspection tool; the first clamping component and the second clamping component clamp the glass from four sides respectively, and the multi-directional fixation ensures the stability of the glass during the testing process and avoids the impact of shaking on the testing accuracy; the lifting and adjusting component can realize flexible adjustment of height and angle.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a glass inspection tool for an excavator cab, including a worktable 1, a lifting and adjusting assembly 2, a first clamping assembly 3, and a second clamping assembly 4.

[0024] The lifting adjustment component 2 is located above the workbench 1. The lifting adjustment component 2 is used to adjust the height and angle of the first clamping component 3 and the second clamping component 4. The first clamping component 3 is located above the lifting adjustment component 2, and the second clamping component 4 is located on the first clamping component 3. The first clamping component 3 and the second clamping component 4 are used to clamp and fix the excavator cab glass.

[0025] Furthermore, the lifting adjustment assembly 2 includes a first lifting push rod 201, a first connecting seat 202, a second lifting push rod 203, a second connecting seat 204, and a first drive motor 205. The first lifting push rod 201 and the second lifting push rod 203 are fixed inside the worktable 1. The first connecting seat 202 is fixed to the top end of the first lifting push rod 201, and the second connecting seat 204 is fixed to the top end of the second lifting push rod 203. The first clamping assembly 3 is disposed between the first connecting seat 202 and the second connecting seat 204. The first drive motor 205 is fixed to the outside of the first connecting seat 202. The first lifting push rod 201 and the second lifting push rod 203 push the first connecting seat 202 and the second connecting seat 204 to lift and lower simultaneously. The first connecting seat 202 and the second connecting seat 204 drive the first clamping assembly 3 and the second clamping assembly 4 to lift and lower. The first drive motor 205 drives the first clamping assembly 3 to rotate, thereby adjusting the angle of the first clamping assembly 3 and the second clamping assembly 4.

[0026] Furthermore, the first clamping assembly 3 includes a first slide rail 301, a lead screw 302, a first slider 303, a second drive motor 304, a second slide rail 305, a second slider 306, a first connecting plate 307, and a first clamping block 308. The first slide rail 301 is rotatably connected to the first connecting seat 202, and the second slide rail 305 is rotatably connected to the second connecting seat 204. The drive shaft of the first drive motor 205 is connected to the first slide rail 301. The lead screw 302 is rotatably connected to the inner side of the first slide rail 301. Two symmetrical first sliders 303 are threadedly connected to the lead screw 302. The second drive motor 304 is fixed to the end of the first slide rail 301, and the drive shaft of the second drive motor 304 is connected to the lead screw 302. Two symmetrical second sliders 306 are symmetrically slidably connected inside the second slide rail 305. The first sliders 303 and second sliders 306 are aligned with each other. The first connecting plate 307 is fixed between the aligned first sliders 303 and second sliders 306, and the first clamping block 308 is fixed on the first connecting plate 307. The first drive motor 205 drives the first slide rail 301 to rotate. Since the first slide rail 301 and the second slide rail 305 are connected to each other, the entire first clamping assembly 3 rotates, thereby changing the angle. The second drive motor 304 drives the lead screw 302 to rotate. The lead screw 302 drives the two first sliders 303 to move closer or further apart. The first sliders 303 drive the second slider 306 to move through the first connecting plate 307, improving the stability of the movement. The first clamping block 308 on the first connecting plate 307 clamps one or both sides of the glass.

[0027] Furthermore, a support rod 309 is fixed between the first slide rail 301 and the second slide rail 305. This improves the synchronization stability between the first slide rail 301 and the second slide rail 305.

[0028] Furthermore, the second clamping assembly 4 includes a mounting plate 401, a clamping push rod 402, a second connecting plate 403, and a second clamping block 404. Mounting plates 401 are disposed above both the first slide rail 301 and the second slide rail 305. A clamping push rod 402 is fixed above each clamping plate. The second connecting plate 403 is fixed to the end of the clamping push rod 402, and the second clamping block 404 is fixed to the second connecting plate 403. By pushing the second connecting plate 403 with the clamping push rod 402, the second clamping block 404 on the second connecting plate 403 clamps the other two sides of the excavator cab glass, improving the clamping effect.

[0029] Furthermore, the first slide rail 301 and the mounting plate 401, and the second slide rail 305 and the mounting plate 401 are all fixed with bolts, so as to facilitate the separation of the second clamping assembly 4 from the first clamping assembly 3.

[0030] In summary, the workflow of this excavator cab glass inspection tool revolves around the clamping, fixing, and position adjustment of the glass. First, the lifting adjustment assembly 2 plays a basic adjustment role, simultaneously pushing the first connecting seat 202 and the second connecting seat 204 up and down via the first lifting push rod 201 and the second lifting push rod 203, thereby driving the first clamping assembly 3 and the second clamping assembly 4 above to achieve height adjustment. Simultaneously, the first drive motor 205 drives the first slide rail 301 to rotate. Since the first slide rail 301 and the second slide rail 305 are connected by the support rod 309, they can drive the entire first clamping assembly 3 and the second clamping assembly 4 to rotate synchronously, completing the angle adjustment.

[0031] In the glass clamping stage, in the first clamping assembly 3, the second drive motor 304 drives the lead screw 302 to rotate, causing two symmetrical first sliders 303 to move closer or further apart along the first slide rail 301. The first sliders 303 drive the second sliders 306 in the second slide rail 305 to move synchronously through the first connecting plate 307, and finally the first clamping blocks 308 on the first connecting plate 307 clamp the two sides of the glass. The second clamping assembly 4, through the clamping push rod 402 on the mounting plate 401, pushes the second connecting plate 403 to move, so that the second clamping blocks 404 clamp the other two sides of the glass, achieving a stable fixation of the glass. In addition, the first slide rail 301 and the mounting plate 401, and the second slide rail 305 and the mounting plate 401 are fixed with bolts, which facilitates the separation of the second clamping assembly 4 from the first clamping assembly 3 and flexibly adapts to different usage requirements.

[0032] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
