Description

A workbench that can precisely adjust the lifting height

technical field

The utility model relates to the mechanical field, in particular to a workbench which can precisely adjust the lifting height.

Background technique

Most of the existing working and processing platforms are fixed on the frame, and the height of the working table cannot be adjusted, which brings some troubles to the production and processing. For example, in some presses, the stroke from the indenter to the working table is usually fixed. It is very troublesome to reset the stroke every time, and some of them cannot even be changed. Although some workbenches can be adjusted in height, the adjustment accuracy cannot be guaranteed. In order to solve these problems, we propose a workbench that can precisely adjust the lifting height .

In order to solve the above technical problems, the utility model provides the following technical solutions: a workbench that can precisely adjust the lifting height, including a frame, a workbench body and a hydraulic support device, screw rods are provided on both sides of the frame, The bottom end of the screw rod is rotatably connected to the lower end surface of the frame through a bearing, the upper end of the screw rod is fixedly connected to the output end of the motor through a coupling, the motor is fixed above the frame, and the two sides of the workbench body There is a rolling thread matched with the screw rod, the screw rod and the rolling thread are engaged with each other, the workbench body is slidably connected to the screw rod through the thread rolling, and a hydraulic support device is provided on the frame below the workbench body. The hydraulic support device includes a hydraulic pump, an output shaft and a support frame, the hydraulic pump is fixed on the bottom surface of the frame, the output shaft is connected to the output end of the hydraulic pump, and the support frame is fixedly connected above the output shaft. The support frame is closely attached to the lower end surface of the workbench body.

Preferably, the workbench body is provided with a temperature sensing device to prevent the operator from being injured.

Preferably, lubricating oil is applied to the joint between the screw rod and the rolling thread to reduce friction and make the screw rod drive the rolling thread more easily.

Preferably, the rotation speed and steering direction of the screw rods on both sides of the frame are the same, and the same control switch is used for the motors connecting the screw rods on both sides, so that the force on both sides of the workbench body is even, and it is easy to lift.

The beneficial effects achieved by the utility model are:

1. Simple structure and convenient operation;

2. It can precisely control the lifting height of the workbench body;

3. The hydraulic support device is used to make the workbench more stable.

detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

As shown in Figure 1, a workbench that can accurately adjust the lifting height of this embodiment includes a frame 1, a workbench body 2 and a hydraulic support device, and screw rods 3 are provided on both sides of the frame 1, and the The bottom end of the screw mandrel 3 is connected to the lower end surface of the frame 1 by bearing rotation, the upper end of the screw mandrel 3 is fixedly connected to the output end of the motor 4 through a shaft coupling, and the motor 4 is fixed above the frame 1, and the working The two sides of the table body 2 are provided with rolling thread 5 matched with the screw rod 3, the screw rod 3 and the rolling thread 5 are engaged with each other, the worktable body 2 is slidably connected to the screw rod 3 through the rolling thread 5, and the The frame 1 below the body 2 is provided with a hydraulic support device, the hydraulic support device includes a hydraulic pump 6, an output shaft 7 and a support frame 8, the hydraulic pump 6 is fixed on the bottom surface of the frame 1, and the output shaft 7 is connected to the output end of the hydraulic pump 6, and the support frame 8 is fixedly connected above the output shaft 7, and the support frame 8 is closely attached to the lower end surface of the workbench body 2.

The workbench body 2 is provided with a temperature sensing device 9 to prevent the operator from being injured. The connection between the screw mandrel 3 and the rolling thread 5 is coated with lubricating oil to reduce friction and make the screw mandrel 3 easier to operate. Drive thread rolling 5, the rotating speed of screw mandrel 3 on both sides of described frame 1 is the same as the direction of rotation, and the motor 4 connecting both sides of screw mandrel 3 adopts the same control switch, so that both sides of workbench body 2 are evenly stressed and easy to lift.

It should be noted that the working process of a workbench that can accurately adjust the lifting height of the utility model is as follows: when adjusting the height of the workbench, the hydraulic support device retracts the support frame 8, and the motor 4 drives the wire to adjust the height according to the needs. The rod 3 rotates, so that the workbench body 2 can move up and down. Since the screw rod 3 has the characteristics of high precision and easy control, the height of the workbench body 2 can be precisely controlled, and finally the hydraulic support device supports the workbench body 2 .
