Description

Technical Field

[0001] The invention relates to the field of sleeper processing, in particular to a sleeper casing spiral rib assembly machine. Background Art

[0002] The sleeper, also known as the sleeper, is a type of railway accessory. The sleeper not only supports the rails, but also maintains the position of the rails, and also transfers the huge pressure transmitted by the rails to the roadbed. It must have a certain degree of flexibility and elasticity, and it cannot be too hard or too soft. When a train passes by, it can be deformed appropriately to buffer the pressure, but it must be restored to its original state as much as possible after the train passes.

[0003] In the processing of cement sleepers, there is a step of installing the embedded sleeve in the sleeper mold and installing the spiral rib spring outside the sleeve. In the previous processing and production, the sleeve is placed manually first, and then the spiral rib spring is tightened with a wrench, but the work efficiency is low and the labor workload of the workers is large. In addition, since the sleeper mold generally adopts an integrated four-cavity, 16 sleeves need to be installed at a time. In order to meet the production rhythm, 2-3 workers are needed to meet the production needs, which wastes manpower. Therefore, it is necessary to develop an automatic assembly equipment for sleeve spiral ribs. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is described in more detail below with reference to embodiments.

[0023] like Figure 1-3 The sleeper casing spiral rib assembly machine shown in the figure comprises a casing conveyor 4, a driven shaft is provided at the left end of the frame of the casing conveyor, a driving shaft is provided at the right end, and a motor 6 is installed on the driving shaft. Sprockets 15 are installed on the driving shaft and the driven shaft, and chains 16 are installed on the sprockets. Several mounting plates 14 are evenly installed on the chain 16, and a conical casing positioning head 13 is fixed on each mounting plate 15. The bottom of the frame is fixed to the ground by bolts.

[0024] A casing arrangement vibration plate 1 is provided on one side of the frame, and the casing arrangement vibration plate 1 arranges the casings in a row and drops them from the outlet. The outlet of the arrangement vibration plate is located directly above the chain; a guide device 5 is provided between the outlet of the arrangement vibration plate and the chain; the guide device includes two relatively arranged guide blocks 51, and both guide blocks are equipped with a driving cylinder 52, which can push the two guide blocks to be assembled into a trumpet-shaped guide cylinder, and the casing positioning head is located at the bottom of the guide cylinder. The driving cylinder 52 is fixed to the frame of the casing conveyor by a fixing member 53. In this embodiment, a proximity switch is used to control the guide mechanism: a proximity switch 55 is provided on the guide device, and a metal head 54 for cooperating with the proximity switch is provided on each mounting plate.

[0025] When the chain sends the casing positioning head to the bottom of the outlet of the arranging vibration plate, the metal head triggers the proximity switch, and the proximity switch sends an electrical signal to the driving cylinder to make the two guide blocks splice into a guide cylinder; the arranging vibration plate drops a casing, and the casing falls on the guide head with the assistance of the guide cylinder.

[0026] In this embodiment, the guide device is also provided with a photoelectric sensor, and the holes on the two guide blocks in the figure are used for photoelectric detection. After the sleeve is placed in place, the photoelectric sensor sends an electrical signal to make the drive cylinder release the guide cylinder to position the next sleeve.

[0027] A clamping mechanism 11 is also provided above the chain, and the clamping mechanism 11 includes two clamping blocks 111 arranged opposite to each other, each of which is provided with a groove consistent with the shape of the sleeve, and each clamping block is provided with a driving cylinder 112; after the sleeve to be installed with the spiral rib is moved to the position of the clamping mechanism, the driving cylinder 112 pushes the clamping block 11, and the grooves on the clamping block clamp and limit from both sides of the sleeve.

[0028] A robotic arm is also provided on one side of the casing conveyor. On one side of the robotic arm are a raw material discharge tray 1 for spiral bending processing, a spiral rib processing machine 2, and a spiral rib processing machine controller 12. The top of the robotic arm is a spiral rib installation head, which can clamp and rotate the spiral rib. When the clamping mechanism 11 clamps the casing to be installed with the spiral rib, the spiral rib installation head on the robotic arm clamps the spiral rib from the spiral rib processing machine 2, then moves to the top of the spiral rib fixed by the clamping mechanism 11, and then rotates the spiral rib to install it on the casing. After the spiral rib is installed, the clamping mechanism 11 is released to carry out the installation process of the next casing.

[0029] A row of multiple mounting heads can be installed on the spiral rib mounting head mechanical arm, so that multiple spiral ribs can be installed at one time. As shown in the figure, two spiral ribs can be installed at one time in this embodiment.

[0030] The above examples are only used to help understand the core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
