Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0025]When the rubber spring clamping work starts, first the rubber spring [39] is placed on the center position of the clamping work disc [28], and the PLC controls the stepper motor II [40] to drive the linear screw [41] to rotate, and the special-shaped nut [42] Under the action of the thread pair, the steel ring support mounting block [36] fixedly connected with it is driven to move upward, and the steel ring support mounting block drives the driving steel ring support [35] fixedly connected with it to move upward, and the rubber spring outer foot The clamping block [38] rotates clockwise under the drive of the clamping connecting rod I [32], and clamps the rubber spring outer pin together with the internal housing [44] of the clamping part. The rubber spring inner foot clamping block [45] then rotates counterclockwise to clamp the rubb...

The invention discloses a new device for automatically removing burrs in the pouring of a series of rubber springs of an EMU, which mainly includes features of a mechanical part and an electrical control part. The features of the mechanical part include the shearing part for burr removal, the opening and closing part for the cutting tool, the frame part for supporting the whole device, and the clamping part for fixing the rubber spring. The cutting part includes inner and outer scissors, scissors sliding bracket, working cylinder, universal joint, etc.; the tool opening and closing part includes composite rail fixing rod, composite rail sliding rod and "V" composite rail bracket, gap sliding rod bracket, Cam, etc.; the frame part includes the upper bracket for installing the motor and the fixed pulley, two parallel and upright "umbrella"-shaped overall support brackets, the support base and the rubber spring clamping part fixing table, etc.; the rubber spring clamping part includes air springs Inner and outer foot clamping blocks and supporting top pieces, driving steel ring brackets, clamping connecting rods, inner and outer shells, etc. The characteristics of the electrical control part include machine vision scanning positioning and PLC electrical control. The scanning positioning of machine vision is based on the vision system expanded and realized with DM642 as the core. The PLC electrical control is composed of solenoid valves, DC motors, linear motors, and stepping motors. And its driver and PLC composition.
Description
technical field [0001] The invention relates to a deburring device, in particular to an automatic deburring device for pouring a series of rubber springs of an EMU. Background technique [0002] A rubber spring is a non-metallic spring that uses the compressibility of air contained in a flexible airtight container to achieve elastic action. Its excellent elastic performance can promote the locomotive to run more smoothly. Therefore, a series of rubber air springs are widely used in locomotives. [0003] According to the current situation, after the rubber spring is poured, the burrs need to be removed before it can be used. However, the existing deburring work is done manually, which consumes a lot of manpower and material resources. According to statistics, there are more than 2,000 pouring burrs in a series of rubber springs that have just been poured. According to the existing work efficiency of 1 per second per person, it takes more than 30 minutes for a rubber spring....
