L-shaped frame assembling jig

Abstract

The invention discloses an L-shaped frame assembling jig. The L-shaped frame assembling jig comprises a bottom plate, a center positioning block fixed to the bottom plate, and two abutting clamping jaws which are slidably arranged on the bottom plate and located on the two sides of the center positioning block; the length and width of the center positioning block correspond to the dimension of thelong side and the dimension of the short side of each L-shaped frame; and the abutting clamping jaws can slidably get close to or away from the center positioning block. According to the L-shaped frame assembling jig, the bottom plate is provided with the center positioning block of which the shape and dimension correspond to those of the two L-shaped frames, and the two abutting clamping jaws, when the two abutting clamping jaws get away from the center positioning block, a feeding mechanical hand of automatic welding equipment can clamp and place the two L-shaped frames on the two sides ofthe center positioning block, then, the abutting clamping jaws slidably get close to the center positioning block and enable the L-shaped frames to abut against the center positioning block, and positioning of the two L-shaped frames is achieved. The two L-shaped frames are positioned with the center positioning block located between the two L-shaped frames as a criterion, moreover, the abutting clamping jaws abut against the L-shaped frames, thus, positioning of the two L-shaped frames is good, relative dislocation is not prone to occurring, and follow-up good welding can be ensured.

Description

technical field [0001] The invention relates to a jig, in particular to an L-frame assembling jig for assembling an L-frame in a vibration motor of a mobile phone. Background technique [0002] figure 1 The two L frames shown are components in the vibration motor of the mobile phone. During the assembly process of the vibration motor, the two L frames need to be assembled as figure 2 Butted into a closed ring as shown in , and welded at two butt positions A, B to fix the two as a whole. During the assembly process, the positioning requirements of the two L frames are high. Once there is a misalignment between the two L frames, welding failure will occur or it will become a defective product after welding. Once the defective product is not found in time, it may affect the performance of the vibration motor. Normal function can even cause the motor to be scrapped. Therefore, it is very important to ensure that the relative positions of the two L frames are well positioned ...

Problems solved by technology

During the assembly process, the positioning requirements of the two L frames are high. Once there is a misalignment between the two L frames, welding failure will occur or it will become a defective product after welding. Once the defective product is not found in time, it may affect the performance of the vibration motor. Normal function even causes the motor to be scrapped

Therefore, it is very important to ensure that the relative positions of the two L frames are well positioned before welding, but currently there is no suitable fixture that can properly position the two L frames in the automatic welding equipment
