Further:
in order to solve the technical problem of fixing the reinforcing rib 1c, as shown in fig. 6, 1, 11 and 12, the following technical solutions are provided:
the fourth fixing structure 6 comprises the fourth fixing structure,

the guide post 6b is axially slidably arranged in the sleeve 6a, one end of the guide post 6b is positioned in the sleeve 6a, and the other end of the guide post 6b abuts against the inclined surface of the reinforcing rib 1 c;
the two clamping plates 6c are symmetrically arranged on two sides of the guide post 6b, one end of each clamping plate 6c is hinged with the sleeve 6a, and the other end of each clamping plate 6c abuts against the side face of the reinforcing rib 1 c;

and an elastic piece 6e, wherein the elastic piece 6e is arranged inside the sleeve 6a, and the elastic piece 6e is used for enabling the guide post 6b to always have the tendency of moving axially outwards.
Specifically, the elastic member 6e is a spring. The mechanical arm 2 drives the fourth fixing structure 6 to move towards the direction of the reinforcing rib 1c, when the guide pillar 6b starts to abut against the upper side of the reinforcing rib 1c, the guide pillar 6b exerts a vertical downward reaction force on the reinforcing rib 1c under the elastic force action of the elastic piece 6e, so that the side surface of the reinforcing rib 1c is tightly attached to the side surface of the connecting block 1b, and the bottom surface of the reinforcing rib 1c is tightly attached to the upper surface of the brake shoe plate 1a 1. On the other hand, the guide post 6b is abutted by the reinforcing rib 1c, the guide post 6b moves upwards relative to the fourth fixing structure 6, the guide post 6b drives the connecting piece 6d to pull upwards, and the connecting piece 6d drives the clamping plate 6c to rotate towards the guide post 6b until the clamping plate 6c clamps two sides of the reinforcing rib 1c, so that the side surface of the reinforcing rib 1c is fixed. The reinforcing bar 1c is thus completely fixed.
The second embodiment is as follows:
the difference from the first embodiment is that:
the fourth fixing structure 6 comprises the fourth fixing structure,
the sleeve 6a is arranged at the output end of the mechanical arm 2;
the guide post 6b is axially slidably arranged in the sleeve 6a, one end of the guide post 6b is positioned in the sleeve 6a, and the other end of the guide post 6b abuts against the inclined surface of the reinforcing rib 1 c;
the two clamping plates 6c are symmetrically arranged on two sides of the guide post 6b, one end of each clamping plate 6c is hinged with the sleeve 6a, and the other end of each clamping plate 6c abuts against the side face of the reinforcing rib 1 c;
and two connecting pieces 6d are arranged, one end of each connecting piece 6d is hinged with the guide post 6b, the other end of each connecting piece 6d is hinged with the clamping plate 6c, and each connecting piece 6d is an elastic piece.
In particular, the connecting member 6d is a spring. The arm 2 drives the fourth fixing structure 6 to move towards the direction of the reinforcing rib 1c, when the guide pillar 6b is supported and fixed by the reinforcing rib 1c, the guide pillar 6b independently moves upwards relative to the whole fourth fixing structure 6, the guide pillar 6b drives the connecting piece 6d to pull upwards, the connecting piece 6d drives the clamping plate 6c to rotate towards the guide pillar 6b until the clamping plate 6c supports the two sides of the reinforcing rib 1c, and the clamping plate 6c stops moving. The guide post 6b continues to move upwards integrally relative to the fourth fixed structure 6, in the process, the guide post 6b drives the connecting piece 6d to stretch, in the stretching process of the connecting piece 6d, the connecting piece 6d gradually applies a vertical downward pulling force to the guide post 6b, and the connecting piece 6d gradually applies a pulling force pointing to the reinforcing rib to the clamping plate 6 c. Under the action of the pulling force of the clamping plate 6c, the guide post 6b applies a vertical downward force to the reinforcing rib 1c, so that the side surface of the reinforcing rib 1c is tightly attached to the side surface of the connecting block 1b, and the bottom surface of the reinforcing rib 1c is tightly attached to the upper surface of the brake shoe plate 1a 1; the clamping plate 6c gradually clamps the reinforcing rib 1c on both sides. Until the reinforcing bar 1c is completely fixed.
Because the connecting piece 6d is a rigid piece in the first scheme, the positions of the guide posts 6b and 6c are relatively fixed, when the reinforcing rib 1c is clamped, the stop position of the fourth fixing structure 6 must be accurate, and if the fourth fixing structure 6 stops early, the clamping plate 6c cannot reach the designated position, and the clamping plate 6c cannot fix the reinforcing rib 1 c; if the fourth fixing structure 6 stops late, the guide post 6b will continue to move away from the clamp 6c, the relative position of the guide post 6b and the clamp 6c will become longer, and the guide post 6b and the clamp 6c will easily tear the connector link 6 d. In the second embodiment, the connecting member 6d is an elastic member, and there is no risk of tearing. Therefore, the second scheme is the preferred scheme of the embodiment.
