Abstract
本发明公开一种液压机移动机构工件托起装置，包括有移动工作台，在移动工作台的内侧底端设置有托板，在托板的上面设置有顶杆，移动工作台的台面上形成有与托板上面的顶杆相对应并可贯穿顶杆的顶杆孔，在工作台的台面上设置有驱动托板上、下移动的托起液压缸。托起液压缸安装在移动工作台的台面内，其中托起液压缸的伸缩结构是通过连接螺母与托板相连接，从而驱动托板带动顶杆上、下移动。移动工作台的台面内设置有4个以上的与托板相连接的托起液压缸。本发明在液压机移动机构中设置了能够单独驱动安装有顶杆的托板上、下移动的液压缸，所以能够使液压机移动机构在任何位置都能够方便、快捷地安装或更换顶杆。
The invention discloses a workpiece lifting device of a moving mechanism of a hydraulic machine, which includes a mobile workbench, a supporting plate is arranged at the inner bottom end of the movable workbench, a push rod is arranged on the upper surface of the supporting plate, and a Corresponding to the ejector rod on the supporting plate and can pass through the ejector rod hole of the ejector rod, a supporting hydraulic cylinder for driving the supporting plate to move up and down is arranged on the table top of the workbench. The lifting hydraulic cylinder is installed in the table of the mobile workbench, wherein the telescopic structure of the lifting hydraulic cylinder is connected with the supporting plate through the connecting nut, thereby driving the supporting plate to drive the ejector rod to move up and down. More than 4 lifting hydraulic cylinders connected with the pallet are arranged in the table of the mobile workbench. In the present invention, a hydraulic cylinder that can independently drive the supporting plate with the ejector rod to move up and down is provided in the hydraulic machine moving mechanism, so the hydraulic machine moving mechanism can be installed or replaced conveniently and quickly at any position.
Description
Technical field
The invention belongs to the travel mechanism of hydraulic press, particularly relate to the supporting plate that a kind of travel mechanism can drive hydraulic press travel mechanism inside at an arbitrary position and move up, can install or change the hydraulic press travel mechanism workpiece picking-up device of the push rod on the supporting plate easily.
Background technology
At present, the structure of the travelling table of the hydraulic press of extensive use is on market, the stand upper support of workbench work top, stand bottom at workbench, be that the downside of work top is provided with under the hydraulic press host computer control can upper and lower mobile backing plate, described backing plate is provided with most push rods, and be formed with on the work top most with backing plate on the corresponding punching in push rod position, when work, hydraulic press host computer control backing plate moves up, and the punching that the push rod on the backing plate runs through on the work top is carried out punching press to workpiece.
The aforesaid backing plate that is provided with push rod, when only being positioned at the main frame position, being subjected to the control of hydraulic press main frame just can drive push rod and moving up, when other position in travel mechanism, the backing plate that is provided with push rod is irremovable, can only be positioned at the stand bottom of workbench.But the quantity that push rod is set on backing plate is need to change at any time along with the different of processed workpiece with the position, gives and changes or install the inconvenience that push rod brings ten minutes.
Also have and to carry out stamping press for a long time, in case when causing the corrupted of push rod, because not in the main frame position, the position of backing plate is not corresponding with travel mechanism, changing push rod is exactly a very difficult thing.
Summary of the invention
The present invention provides a kind of when hydraulic press is not worked for solving the technical problem that exists in the known technology, the supporting plate that also can drive the hydraulic press workbench moves up, and can install or change the hydraulic press travel mechanism workpiece picking-up device of the push rod on the supporting plate easily.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of hydraulic press travel mechanism workpiece picking-up device, include travelling table, inboard bottom at travelling table is provided with supporting plate, on supporting plate, be provided with push rod, be formed with corresponding with the push rod above the supporting plate on the table top of described travelling table and can run through the jogger hole of push rod, the table top of workbench is provided with and drives the upper and lower mobile picking-up hydraulic cylinder of supporting plate.
Described picking-up hydraulic cylinder is installed in the table top of travelling table, and the stretching structure that wherein holds up hydraulic cylinder is to be connected with supporting plate by the attaching nut, thereby drives upper and lower the moving of supporting plate drive push rod.
Be provided with the picking-up hydraulic cylinder that is connected with supporting plate more than 4 in the table top of described travelling table.
Advantage and good effect that the present invention has are: because hydraulic press of the present invention travel mechanism workpiece picking-up device, being provided with drive installation separately in hydraulic press travel mechanism has the upper and lower mobile hydraulic cylinder of supporting plate of push rod, so can make hydraulic press travel mechanism can both install or change push rod quickly and easily in any position.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, hydraulic press of the present invention travel mechanism workpiece picking-up device, include travelling table 3, inboard bottom at travelling table 3 is provided with supporting plate 2, on supporting plate 2, be provided with push rod 4, be formed with corresponding with the push rod 4 above the supporting plate 2 on the table top of described travelling table and can run through the jogger hole 5 of push rod 4, the table top of workbench is provided with and drives supporting plate 2 upper and lower mobile picking-up hydraulic cylinders 1.Described supporting plate 2 is to be connected with the table top of travelling table 3 by holding up hydraulic cylinder 1.
As shown in Figure 2, described picking-up hydraulic cylinder 1 is installed in the table top of travelling table 3, and the stretching structure that wherein holds up hydraulic cylinder 1 is to be connected with supporting plate 2 by the attaching nut, thereby driving supporting plate 2 drives push rod 4 upper and lower the moving on it.And in the table top of travelling table 3, be provided with the picking-up hydraulic cylinder 1 that is connected with supporting plate 2 more than 4.
Hydraulic press of the present invention travel mechanism workpiece picking-up device, before hydraulic press work, need install or when changing push rod 4 according to the structure of processed workpiece, or damage when changing push rods 4 because of push rod 4, can start the picking-up hydraulic cylinder 1 that is arranged in the work top, hold up hydraulic cylinder 1 and move up by coupled supporting plate 2 drive push rods 4, thereby, make push rod on the supporting plate 2 run through the jogger hole 5 on the work top, can change push rod easily.
