To achieve the above object, a kind of loop test machine for lifting platform, including rack, testboard, test branch are designed
Frame, straight line die set, driving motor, it is characterised in that: rack is equipped with testboard, and the rear side positioned at testboard is equipped with test
One end of bracket, the test bracket is cuboid column structure, and test bracket is equipped with straight line die set, straight line
One end of die set connects driving motor, and the other end of straight line die set connects hoisting cross beam；On the hoisting cross beam
It is laid with several connectors.
Straight line die set includes shell, linear guide, sliding block, ball screw, the driving axis connection ball of driving motor
The other end of one end of screw rod, ball screw is located in the shell of straight line die set, and connection sliding block on ball screw is described
The front end of sliding block connects hoisting cross beam, and the left and right ends of sliding block are separately connected linear guide, and linear guide is fixed in shell.
Several support bases are equipped with positioned at the front side of testboard.
The quantity of the connector and the quantity of support base are consistent, and the front-rear position phase of connector and support base
It is corresponding.
The hoisting cross beam is rectangular faceplate structure.
The drive shaft of the driving motor is connect with ball screw, and driving motor passes through connection electrical control
Case.
The utility model compared with the existing technology, provides a kind of loop test machine for lifting platform, to a batch of
Product random sampling is tested, while being got stuck and the test in service life, guarantees that the quality of product reaches the requirement of client, is dropped
Low subsequent workload after sale, and avoid the outflow of substandard product.
Detailed description of the invention
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structural side view.
Fig. 3 is straight line die set structural schematic diagram.
It is straight line die set referring to Fig. 1 to Fig. 3,1,1-1 is ball screw, and 1-2 is sliding block, and 1-3 is linear guide, 1-
4 be shell, and 2 be electric control box, and 3 be support base, and 4 be rack, and 5 be hoisting cross beam, and 6 be test bracket, and 8 be connector, and 9 are
Bracket upper arm, 10 be testboard, and 11 be driving motor.
Specific embodiment
The utility model is described further below according to attached drawing.
As shown in Figure 1 to Figure 3, rack 4 is equipped with testboard 10, and the rear side positioned at testboard 10 is equipped with test bracket 6
One end, the test bracket 6 is cuboid column structure, and test bracket 6 is equipped with straight line die set 1, straight line mould
One end of group component 1 connects driving motor 11, and the other end of straight line die set 1 connects hoisting cross beam 5；The hoisting cross beam
Several connectors 8 are laid on 5.
Straight line die set 1 includes shell, linear guide, sliding block, ball screw, and the driving axis connection of driving motor 11 is rolled
The other end of one end of ballscrew 1-1, ball screw 1-1 is located in the shell 1-4 of straight line die set 1, on ball screw 1-1
The front end of connection sliding block 1-2, the sliding block 1-2 connect hoisting cross beam 5, and the left and right ends of sliding block 1-2 are separately connected straight line and lead
Rail 1-3, linear guide 1-3 are fixed in shell 1-4.
Several support bases 3 are equipped with positioned at the front side of testboard 10.
The quantity of connector 8 is consistent with the quantity of support base 3, and connector 8 is opposite with the front-rear position of support base 3
It answers.
Hoisting cross beam 5 is rectangular faceplate structure.
