Abstract
The invention discloses a square ram of which the ram body is in a right four-edge object structure. Two side faces corresponding to the ram body are respectively provided with a guide rail pair; the ram body is formed by matching and welding a cover body and four side panels, wherein the cover plate forms the bottom of a four-edge object and is reserved with a milling head installing hole and the side panels are reserved with accessory installing assembly holes and technique holes; at least one vertical rib plate is radially arranged on each side panel in the space formed after welding, and a set of circumferential rib plates reserved with the milling head installing hole is radially arranged along the ram body in the space, wherein four edges of the circumferential rib plates are welded to the side panels; and the guideway pairs are installed on the side panels through bolts. The scheme can greatly reduce the weight of the square ram in the condition of meeting the structure strength, and simultaneously meet the technical requirements of short production period and easy subsequent assembly.
Description
Technical field
The present invention relates to a kind of side's ram, specifically relate to a kind of square ram that is applied to numerical control five-axle interlock machining tool, ram body that wherein should side's ram is positive four bank or ridge structure.
Background technology
Known side's ram is the cast-in-block structure, and known founding materials all is the not high material of intensity, and ram exactly requires than higher intensity, and the guide rail set-up mode of square ram uniqueness requires himself structure to be complementary with guideway, in order to satisfy above-mentioned two conditions, must make that the volume ratio of ram body is bigger, and then cause the ram body weight bigger than normal, can't satisfy five-axle linkage high-speed processing machine tool requirement underloading, the fast requirement of dynamic response, run counter to the requirement of relevant moving member loss of weight at present; Will assemble milling head on the ram in addition, need carry out multistage processing on the ram body that casting is finished, the production cycle is long.
In addition, also various annexes and cabling will be installed on the ram body that casting forms, corresponding mounting structure is difficult under the casting condition to be finished, and can only not only make the production cycle of ram long partially by follow-up machining, and processing difficulties.
For sake of convenience, below to doing some supposition: the ram body is positive four bank or ridge structure, and its short transverse is defined as axially so, correspondingly, certainly leads to corresponding circumferential notion.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of square ram of new structure,, satisfy specification requirement with short production cycle, that be convenient to follow-up assembling simultaneously satisfying under the situation of structural strength the significantly weight of the side's of reduction ram.
The present invention is by the following technical solutions:
This side's of invention ram, its ram body is positive four bank or ridge structure, and two sides relative at this ram body respectively are provided with the pair of guide rails pair, described ram body is welded by the cover plate that is reserved with the milling head installing hole that forms positive four bank or ridge bottom surface and four side panels collocation that are reserved with annex installation component and fabrication hole, and on each side panel, at least radially be provided with a vertical gusset in the space that after welding, forms, and in described space, radially be provided with one group of circumferential gusset that is reserved with the milling head installing hole along the ram body, wherein circumferentially four side welds of gusset are connected on the side panel; Described guideway is installed on the side panel by bolt.
The ram body of the square ram of foundation technical scheme of the present invention adopts the integral solder structure, and under the situation that satisfies installation and structural strength, weight can significantly reduce so.Simultaneously, the ram body that integral solder forms is wider than the selection range of the ram body of casting, the high-strength alloy structural steel or other the steel that are applied to machine industry at present all can use, and certainly, select for use the higher material of intensity can better reduce the weight of ram body.
Simultaneously, in order to satisfy the requirement of structural strength, this programme further is provided with compound reinforcing plate structure in the ram body of welding fabrication, and its structural strength is further improved.
Further, form the part that needs on each member of ram body to install or have other functions and all can carry out preprocessing, not only easy to process, and be easy to guarantee crudy.
Above-mentioned side's ram, described vertical gusset and circumferential gusset entire arrangement adopt limited element analysis technique to determine.
Above-mentioned side's ram, described vertical gusset and circumferential gusset adopt the structural alloy steel of hot strength greater than 430MPa; The line slideway of described guideway adopts the high-quality structural steel of hot strength greater than 710MPa.
Above-mentioned side's ram, described circumferential gusset is reserved with the hole that is used for the milling head cabling.
Above-mentioned side's ram, described guideway comprise the line slideway that is installed on the respective side panel and form the slide block of guideway and the way block that is used to connect slide carriage that is positioned at the milling head end of line slideway with this line slideway.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention, and partly cut-away shows ram body internal structure among the figure.
Among the figure: 1, milling head, 2, way block, 3, way block, 4, preformed hole, 5, pressing plate, 6, slide block, 7, cover plate, 8, circumferential gusset, 9, vertical gusset, 10, line slideway.
The specific embodiment
With reference to Figure of description 1 side's ram, it shows a kind of side's ram, its ram body is positive four bank or ridge structure, and two sides relative at this ram body respectively are provided with the pair of guide rails pair, described ram body is welded by the cover plate that is reserved with milling head 1 installing hole 7 that forms positive four bank or ridge bottom surface and four side panels collocation that are reserved with annex installation component and fabrication hole, and on each side panel, at least radially be provided with a vertical gusset 9 in the space that after welding, forms, and in described space, radially be provided with one group of circumferential gusset 8 that is reserved with the milling head installing hole along the ram body, wherein circumferentially four side welds of gusset are connected on the side panel; Described guideway is installed on the side panel by bolt.
Can also adopt other releasable connection mode about guideway, such as riveted joint, bonding strength is higher, and just each dismounting needs to destroy connector.
For the reasonable disposition gusset, described vertical gusset and circumferential gusset entire arrangement adopt limited element analysis technique to determine.
Preferably, described vertical gusset and circumferential gusset adopt the structural alloy steel of hot strength greater than 430MPa; The line slideway 10 of described guideway adopts the high-quality structural steel of hot strength greater than 710MPa.Naturally said hot strength is high more good more, but the high more material cost of hot strength is good more, needs producer according to own balance of needs work.
Described circumferential gusset is reserved with the hole that is used for the milling head cabling, is convenient to assembling.
Further, described guideway comprises the line slideway that is installed on the respective side panel and forms the slide block 6 of guideway and the way block 3 that is used to connect slide carriage that is positioned at the milling head end of line slideway with this line slideway.This can think directly to divert present guideway set-up mode, just from angle of assembling, because the side panel thickness that guide rail was installed on is even, is convenient to assembling.
