Description

Technical Field

[0001] This utility model relates to the field of fixtures, and more particularly to welding fixtures, especially a welding fixture for interlocking parts of a lower door interlocking mechanism. Background Technology

[0002] The interlocking components with rods on the mounting plate in the switch cabinet are important parts, serving to support the components on the switch cabinet and toggle the switches. However, traditionally, these interlocking components are welded together manually, which is not only inaccurate but also inefficient. Therefore, there is an urgent need in the market for a high-efficiency welding fixture for interlocking components to improve welding efficiency, ensure accuracy, and reduce production costs.

[0003] Chinese utility model patent CN 203475993 U discloses a cabinet upper and lower door interlocking mechanism. This lower door interlocking mechanism is located between the upper and lower doors of a cabinet. The mechanism includes a horizontally movable push rod connected to a first wedge block with a downward-sloping surface. A second wedge block cooperates with the first wedge block, and the inclined surfaces of the two wedge blocks engage and slide against each other. The second wedge block connects to a vertically movable follower, which is connected to a vertically positioned locking rod. The locking rod has an elastic element for resetting its upward movement. A locking plate with a lock hole is located opposite the locking rod and is fixed to the lower door of the cabinet. The interlocking components of this lower door interlocking mechanism lack specialized welding fixtures and require manual placement and welding, resulting in low efficiency and high precision. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a welding fixture for interlocking components of a lower door interlocking mechanism that can quickly clamp the mounting plate and the rod together, facilitating subsequent precise welding. This meets the requirements for fast and high-precision welding of the rod onto the mounting plate.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This lower door interlocking mechanism uses a welding fixture for interlocking parts, including a base. Three square-shaped support blocks with a notch on one side are fixed on the base. Each support block has an elastic clamping element on its open end side. The elastic clamping element includes a seat fastened to the base by fasteners, a bolt inserted into the seat, and a pressure block threaded onto the outer end of the bolt. A compression spring is installed between the pressure block and the seat. A suspension is fixed on the base, and a slot is opened on the suspension. The slot communicates with the outer end face and matches the position of the three square-shaped support blocks. A vertical plate is fixed to the base at the opposite position of the suspension. A cylinder is fixed on the vertical plate, and a clamping rod is fixed on the piston rod of the cylinder. The function of the three square-shaped support blocks with a notch and the elastic clamping element is to clamp the mounting plate and prevent it from moving. The function of the suspension, slot, vertical plate, clamping rod, and cylinder is to properly position and clamp the rod, preventing it from moving.

[0006] Further improvements include the inclusion of a pair of opposing magnets embedded in the inner end face of the slot. The purpose of these magnets is to ensure that when the rod is inserted into the slot, it is held in place by the magnets, preventing it from tipping outwards and providing favorable conditions for the subsequent cylinder to press the rod laterally through the clamping rod.

[0007] Further improvements include a self-lubricating layer on the bottom surface of the pressure block. This self-lubricating layer ensures smoother movement of the pressure block, reducing frictional resistance and preventing jamming. The self-lubricating layer is made of tin bronze.

[0008] Further improvements include adjustable feet connected to the four corners of the base, with tightening nuts threaded onto each foot. The purpose of these adjustable feet and nuts is to allow the base to be adjusted in length on uneven surfaces, adapting to different terrains and ensuring greater stability during use. After adjusting the feet, the nuts are tightened to prevent loosening over time.

[0009] The beneficial effects of this utility model are:

[0010] 1) The mounting plate can be clamped by three square-shaped positioning blocks with a notch on one side and elastic clamping components;

[0011] 2) The rod can be properly installed and clamped using the suspension, slots, vertical plates, clamping rods, and cylinders;

[0012] 3) The self-lubricating layer allows the pressure block to move more smoothly and avoids jamming;

[0013] 4) By adjusting the feet and tightening the nuts, the base can be stably supported, allowing it to be placed smoothly on uneven surfaces. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Referring to the attached diagram: This lower door interlocking mechanism uses a welding fixture for interlocking components, including a base 1. Three square-shaped support blocks 2 with a notch on one side are fixed on the base 1. Each support block 2 has an elastic clamping element 3 on the side of its open end. The elastic clamping element 3 includes a seat 3-1 fastened to the base 1 by fasteners. A bolt 3-2 is inserted into the seat 3-1. The outer end of the bolt 3-2 is threaded with a pressure block 3-3. A compression spring 3-4 is installed between the pressure block 3-3 and the seat 3-1. A suspension 4 is fixed on the base 1. The suspension 4 has a slot 4-1 that communicates with the outer end face. The slot 4-1 matches the position of the three square-shaped support blocks 2. A vertical plate 5 is fixed to the base 1 at the opposite position of the suspension 4. A cylinder 6 is fixed on the vertical plate 5. A clamping rod 6-1 is fixed on the piston rod of the cylinder 6.

[0020] A pair of opposing magnets 4-2 are embedded in the inner end face of slot 4-1.

[0021] The bottom surface of the pressure block 3-3 is provided with a self-lubricating layer 3-3a.

[0022] The base 1 has four threaded connections for adjusting feet 7, and each adjusting foot 7 has a threaded connection for tightening nuts 7-1.

[0023] The working principle of this utility model is as follows: First, the mounting plate 8-1 is placed between the three positioning blocks 2 and the pressure block 3-3 is pressed, thereby compressing the compression spring 3-4 and elastically pressing the side of the mounting plate 8-1. Next, the rod 8-2 is inserted into the slot 4-1, with the bottom end of the rod 8-2 abutting against the top surface of the mounting plate 8-1 and held in place by the magnet 4-2 to prevent it from tipping over. Finally, the cylinder 6 is activated, thereby driving the pressing rod 6-1 to press the side of the rod 8-2, thus stabilizing the position between the mounting plate 8-1 and the rod 8-2. Finally, the welding area 8-3 between the mounting plate 8-1 and the rod 8-2 is welded together by manual labor or a robotic arm, thus completing the processing of the interlocking part 8. The processing efficiency is high, the precision is high, and the processing cost is low, making it worthy of widespread application.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
