[0002] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can close, carry, and break the current under abnormal circuit conditions within a specified time. During the production process of a circuit breaker, it is necessary to mark on the A side and B side of the circuit breaker (as Figure 1 shown), and the marking content includes brand logos, interface information, certification logos, etc.

[0003] Existing laser marking machines can mark objects in the same plane. When marking a circuit breaker, due to the height difference between the two marking surfaces of the A side and the B side, generally, after marking the A side at a high position, it is necessary to adjust the laser marking machine to reduce its focal length so that it can mark the B side at a low position. The adjustment is cumbersome, time-consuming, and consumes a lot of manpower, and is not suitable for mass production; or mark a batch of circuit breakers in two rounds. First, uniformly mark the A side of all circuit breakers. After all the A sides of the circuit breakers are marked, then adjust the focal length of the laser marking machine, and mark the B sides of this batch of circuit breakers for the second time. This marking method requires the turnover of a large number of circuit breakers, occupies production space, and it takes two rounds of marking to completely mark a circuit breaker, and the waiting time is very long, delaying subsequent processes and affecting the production efficiency of products.

[0022] Combined with Figures 1 to 4 It can be seen that an auxiliary tooling for breaker marking includes a bottom plate 1 arranged within the marking range of a marking machine. The surface of the bottom plate 1 is the first placement surface, and a cushion block 2 is provided on the bottom plate. The upper end surface of the cushion block 2 is the second placement surface, and the height difference between the first placement surface and the second placement surface is the same as the height difference between two marking surfaces of different horizontal heights of the breaker.

[0023] A first positioning block 3 is provided on the bottom plate 1 on one side of the cushion block 2. The first positioning block 3 abuts against the cushion block 2, and the side of the first positioning block 3 that abuts against the cushion block 2 forms a positioning right angle 4 that matches one corner of the breaker. During positioning, the breaker is matched with the positioning right angle, one surface of the breaker abuts against the first positioning block 3, and one surface abuts against the cushion block 2.

[0024] A second positioning block 5 is provided on the upper end surface of the cushion block 2. A positioning notch 6 runs through the second positioning block 5, and the width of the positioning notch 6 is adapted to the width of the breaker. The breaker located on the second placement surface is placed in the positioning notch 6 for positioning, facilitating accurate marking.

[0025] The second positioning block 5 includes a transverse block 7 and longitudinal blocks 8 provided at both ends of the transverse block 7. A positioning notch 6 is formed between the transverse block 7 and the two longitudinal blocks 8. The breaker is slidably placed between the two longitudinal blocks 8 and one end thereof abuts against the transverse block 7. Preferably, the transverse block 7 and the longitudinal blocks 8 are integrally provided.

[0026] Preferably, the spacer block 2 is formed by stacking and fixing a plurality of shims 9. A plurality of first positioning holes are provided on the shim 9. Each first positioning hole on each shim 9 is coaxially arranged with the corresponding first positioning hole on other shims 9 and is fixed through a positioning bolt 10 passing through. The lower end of the positioning bolt 10 is threadedly connected to the bottom plate 1. The diameter of the bolt part of the positioning bolt 10 is matched with the diameter of the first positioning hole. The bolt head of the positioning bolt 10 is matched with the bottom plate to press and fix the spacer block 2 and the second positioning block 5.

[0027] A plurality of second positioning holes corresponding to the first positioning holes one by one are provided on the second positioning block 5.

Optionally, the second positioning block 5 can be formed by stacking and fixing a plurality of metal sheets and its height can also be adjusted as needed.

[0028] The working principle of an auxiliary tooling for marking a circuit breaker provided by the utility model is as follows: When in use, first place two circuit breakers on the first placement surface and the second placement surface respectively (the second placement surface can be vacant without placing a circuit breaker). Positioning is carried out through the positioning right angle 4 and the positioning notch 6. The B surface of the circuit breaker located on the second placement surface is raised to the same height as the A surface of the circuit breaker located on the first placement surface through the spacer block 2. When marking, the A surface and the B surface of the two circuit breakers in the same plane can be marked. Subsequently, place the circuit breaker on the first placement surface onto the second placement surface, place a new circuit breaker on the vacant first placement surface, and mark again. At this time, the A and B surfaces of the circuit breaker located on the second placement surface have been marked. Repeating the above steps can achieve rapid marking of the circuit breaker, reduce the adjustment time, and has a high marking efficiency, which is suitable for batch marking.
