Description

A welding fixture for the handlebars of a small excavator Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to a welding tooling for the handle of a small excavator. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding usually requires the use of welding fixtures, which are a set of flexible welding fixtures for fixing, clamping and positioning. They are used for welding various weldable materials, including large, medium and small materials.

[0003] Currently, existing welding fixtures for excavator handlebars are often used for components on large excavators. However, there are often no suitable welding fixtures for welding handlebars on small excavators. This makes it inconvenient to fix the position when welding handlebars on small excavators, resulting in low welding efficiency and failing to meet the user's needs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a welding fixture for the handlebars of mini excavators. This fixture overcomes the deficiencies of existing technologies and effectively solves the problem that there is often no suitable welding fixture for welding the handlebars of mini excavators, which makes it inconvenient to fix the position during welding and thus leads to low welding efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding fixture for the handle of a small excavator includes a base plate. A support rod is fixed to one top corner of the base plate, and a support plate is fixed to the top of the support rod. A fixing rod is fixed to the top of the support plate, and a positioning ring is fixed to the top of the fixing rod. A fixing plate is fixed to one outer wall of the support rod, and fastening mechanisms are provided at the top of the fixing plate and the other top corner of the base plate. A connecting plate is fixed to one top side of the base plate, and a positioning block is connected to the top of the connecting plate.

[0007] Place the mini excavator's handlebar against one side of the positioning block. Then, use the positioning ring and the positioning holes on the positioning block to calibrate the position of the mini excavator's handlebar component. Next, rotate the handle screw in the fastening mechanism to move the pressure block downwards, and fasten both ends of the mini excavator's handlebar to the bottom of the pressure block, thus completing the fastening of the mini excavator's handlebar and facilitating subsequent welding operations.

[0008] Preferably, the fastening mechanism includes an L-shaped frame, a handle screw screwed to one end of the top of the L-shaped frame, and a pressure block fixed to the bottom of the handle screw, wherein a rubber sheet is adhered to the bottom of the pressure block.

[0009] The two ends of the handrail are clamped and fixed by a fastening mechanism, and the friction between the pressure block and the two ends of the handrail is increased by the rubber sheet.

[0010] Preferably, a mounting plate is fixed to the bottom of one side of the inner wall of the L-shaped frame, and mounting holes are provided at both ends of the top of the mounting plate.

[0011] The fastening mechanism is connected and fixed to the base plate and the support plate respectively through the mounting plate.

[0012] Preferably, a connecting rod is fixed to the outer wall of the other side of the support rod, and the end of the connecting rod away from the support rod is connected and fixed to the connecting plate.

[0013] The support rod and the connecting plate are connected and fixed by a connecting rod, which improves the stability of the connecting rod and the support rod.

[0014] Preferably, the positioning block has symmetrical positioning holes on its front side and a lead screw fixed to its back side.

[0015] Positioning and limiting are achieved through positioning holes, enabling quick clamping and improving work efficiency.

[0016] Preferably, the top of the connecting plate is provided with a groove, and the groove is in sliding fit with the lead screw. A locking nut is provided on one side of the groove, and the locking nut is screwed to the lead screw.

[0017] The positioning block is secured to the connecting plate by screwing the lock nut to the lead screw.

[0018] The beneficial effects of this utility model are as follows:

[0019] By placing the mini excavator's handlebar against one side of the positioning block, and then calibrating the position of the handlebar component using the positioning ring and positioning holes on the positioning block, the handle screw in the fastening mechanism is rotated to move the pressure block downwards, thus fastening both ends of the mini excavator's handlebar to the bottom of the pressure block. This completes the fastening of the mini excavator's handlebar, facilitating subsequent welding operations. This effectively solves the problem in existing technologies where there are often no suitable welding fixtures for welding mini excavator handlebars, leading to inconvenience in fixing the position during welding and resulting in low welding efficiency.
