Description

Roller bed

technical field

The invention relates to a workpiece conveying device, in particular to a roller bed.

Background technique

In industrial production activities, it is often necessary to use the conveying device to transport the workpiece to a certain station for processing; at present, the conveying device of the roller bed is often used to realize the conveying and processing of auto parts, but because the roller bed There are pulleys, so the traditional roller bed cannot position the workpiece, so the traditional roller bed structure cannot directly implement the positioning process of the workpiece on the roller bed; at the same time, the power of the traditional roller bed is all driven by the motor, which is not Suitable for some flammable and explosive occasions.

The present invention aims to solve the above-mentioned deficiencies in the prior art, and proposes a roller bed with simple structure and ingenious design, which can directly clamp, position and process workpieces after they are transported in place.

The technical solution of the present invention is: a roller bed, characterized in that: the roller bed includes a first bed body 1 and a second bed body 2, and two rows of outer beds are arranged symmetrically along the axial direction of the first bed body 1. The roller group 3 is slidably connected with the driving frame 4 on the axis of the first bed body 1, the driving frame 4 is provided with a driving chain 5, the driving chain 5 is provided with a driving block 6, and the roller group 3 is provided with a tray 7. The bottom surface of the tray 7 is provided with a stop bar matching the drive block 6, and a first air cylinder 8 connected with the drive frame 4 is also provided in the first bed body 1, and a first cylinder 8 connected with the drive frame 4 is provided on the second bed body 2. The matching groove 9 of the end of the drive frame 4 is provided with a two-way cylinder 10 on the axis of the second bed body 2, and a deck 12 is arranged on the working end of the two-way cylinder 10 near the direction of the first bed body 1, along the The axial direction of the second bed body 2 is also provided with two rows of inner roller sets 13 symmetrically. The inner roller sets 13 include a lifting rod 14, and a plurality of swing rods 15 are uniformly hinged on the lifting rod 14, each The bottom ends of each swing rod 15 are all hinged with the base fixedly arranged on the second bed body 2, and one end of the lift rod 14 is also hinged with the working end of the lifting cylinder 17 which is arranged obliquely, on the second bed body 2 Also be provided with pneumatic clamp group 11 on it.

Compared with the prior art, the present invention has the following advantages:

The roller bed of this kind of structure has simple structure, ingenious design and reasonable layout. It aims at the defect that the traditional roller bed structure can only be used to transport the workpiece, but cannot clamp and position the workpiece so as to directly process it. The roller bed structure is designed as two separate beds (the first bed and the second bed), where the first bed outside the machining center can transport the workpiece to the second bed inside the machining center, The second bed body can move the pallet and the workpiece in place and lift the pallet. At the same time, the pallet is clamped and positioned by the pneumatic clamp group, and the workpiece is directly processed by the machining center; and all the roller beds in this embodiment The drive part adopts telescopic cylinders, which can be used in occasions containing flammable and explosive gases. The manufacturing process of this roller bed is simple and the manufacturing cost is low, so it can be said that it has possessed various advantages, and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

detailed description

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Figures 1 to 4: a roller bed, which includes a matched first bed body 1 and a second bed body 2, and two rows of outer roller sets 3 are arranged symmetrically along the axial direction of the first bed body 1, It is used to support the tray 7 placed on it, and a drive frame 4 is also slidably connected to the axis of the first bed body 1. The drive frame 4 is provided with a rotatable drive chain 5, and a drive block is provided on the drive chain 5. block 6, and on the bottom surface of the tray 7 is also provided with a stopper that matches the drive stopper 6, and the second bed 1 is provided with a first Cylinder 8, and then be provided with the groove 9 that matches with the end of drive frame 4 on the second bed body 2, be provided with two-way cylinder 10 on the axis of second bed body 2, be close to first on this two-way cylinder 10 On the working end of the direction of the bed body 1, a card seat 12 matching the bottom surface of the tray 7 is provided, and two rows of inner roller sets 13 are symmetrically arranged along the axial direction of the second bed body 2, and the inner roller sets 13 includes a lifting rod 14, and on the lifting rod 14, a plurality of swing rods 15 are uniformly hinged, and the bottom ends of the swing rods 15 are hinged to the base fixedly arranged on the second bed body 2 , and one end of the lifting rod 14 is also hinged with the working end of the tilting lifting rod 17 , and a pneumatic clamp group 11 is also arranged on the second bed body 2 for clamping and fixing the pallet 7 .

The working process of the roller bed of the embodiment of the present invention is as follows: first, the craftsman who needs to be transported and processed is placed on the pallet 7, and then the device is turned on. When the drive chain 5 rotates, the drive block 6 on it will pass through the push block. The way of strips drives the tray 7 to move along the axial direction of the first bed 1. During the movement of the tray 7, the outer roller group 3 on the first bed 1 rolls and supports it; the tray 7 moves to the first bed At the end of the body 1, the first cylinder 8 pulls the drive frame 4 to move towards the direction of the second bed body 2 until the end of the drive frame 4 stretches into the groove 9 of the second bed body 2, which is equivalent to The first bed body 1 and the second bed body 2 are connected through the drive frame 4, the second bed body 2 is located in the working range of the machining center, and the tray 7 moves to the second bed body under the drive of the chain 5 on the drive frame 4 body 2, and is rollingly supported by the inner roller group 13 on the second bed body 2, at this time, the pallet 7 is driven by the deck 12 on the two-way cylinder 10; After moving in place under the action, start the lifting cylinder 17, and the lifting cylinder 17 can drive the two lifting rods 14 to move. Swing from the initial horizontal state to the vertical state, the level of the lifting rods 14 rises, and the two lifting rods 14 will lift the pallet 7, and then the pallet 7 will be lifted by the pneumatic clamp group 11 on the second bed body 2. 7 Clamping and positioning, the machining center can process the workpiece on the pallet 7.

After the processing is completed, the lifting rod 14 puts the tray 7 down, and the tray 7 is supported by the inner roller group 13 again, and the two-way cylinder 10 reversely moves, and the tray 7 is returned to the working range of the drive frame 4, and the drive frame 4 Transport the pallet 7 back to the initial position on the first bed body 1, the operator removes the processed workpiece from the pallet 7, and places a new workpiece to be processed on the pallet 7 again to process the next workpiece .
