Abstract
The invention relates to a cutting torch lifting mechanism used in numerical control flame/plasma cutting equipment, comprising an installation frame arranged in a shell; the installation frame is provided with a driving motor; an output shaft of the driving motor is downwards connected with a screw rod; the shell is internally provided with a lifting rod; one side of the lifting rod is provided with a stroke switch control panel; the bottom end of the lifting rod is provided with a cutting torch installation part which extends out of the shell; the shell is internally provided with a guiding block provided with a guide trough; the lifting rod is connected in the guide trough in a sliding way; the screw rod is externally provided with a screw seat matched with the screw rod; the screw seat is fixedly connected with the lifting rod downwards. The cutting torch lifting mechanism of the invention adopts a linear guideway pair composed of the lifting rod and the guiding block and adds the screw seat to replace the existing guide wheel used for clamping the lifting rod; therefore, the cutting torch lifting mechanism has the advantages of simple assembly, more stable and reliable mechanical motion, and leads the cutting torch to enlarge the stroke range.
Description
Technical field
The present invention relates to a kind of cutting torch lifting mechanism, specifically be applied to the cutting torch lifting mechanism in digital control flame/plasma cutting machines, belong to the welding and cutting device technical field.
Background technology
At present, the cutting torch lifting mechanism that uses in digital control flame/plasma cutting machines, its lifting travel is shorter, and range can only reach 150mm, can not satisfy the requirement of some cuttings than heavy-gauge sheeting.The processing of elevating lever in the former cutting torch lifting is difficult, bar domestic demand processing screw screw thread, and the process-cycle is longer, and clamps this elevating lever with 4 directive wheels during assembling, and cooperates with screw mandrel, requires high assembling difficulty, and the gap is difficult to adjustment; Corresponding manufacturing cost height, operating efficiency is lower.And this cutting torch lifting mechanism can only be used for the less flame cutting torch of load, can not be used for bigger plasma cutting-torch of load and dusting device.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, accurate positioning, assembling easy, operate steadily, cutting torch lifting mechanism reliably.
According to technical scheme provided by the invention, described cutting torch lifting mechanism, be included in and be set with installing rack in the housing, on installing rack, be provided with drive motors, the output shaft of described drive motors is connected with screw mandrel downwards, in housing, be provided with elevating lever, be provided with the travel switch control panel in elevating lever one side, the bottom of elevating lever is provided with the cutting torch installed part that stretches out housing, be provided with guide pad in housing, offer gathering sill on the guide pad, described elevating lever is slidingly connected in the gathering sill, outside screw mandrel, be provided with the nut seat that is mated, on described nut seat, be fixedly connected with elevating lever downwards.
Stretch out the outer resilient telescopic of elevating lever overcoat of housing.Described guide pad has two, and they present in housing down and be provided with, and the guide pad that is positioned at the bottom is arranged on the base plate of housing.Described drive motors is a direct current generator.
The present invention adopts the line slideway auxiliary that is made of elevating lever and guide pad, what the replacement of increase nut seat was original clamps elevating lever with directive wheel, make that assembling is easy, mechanical action is more steady, and is reliable, and line slideway auxiliary has also enlarged the stroke range of cutting torch, make range can reach 200mm, substantially can satisfy the split requirement of all thickness sheet material, good processing accuracy, cutting efficiency height; The motor that this cutting torch lifting is adopted can satisfy than heavy load, enables to be used for plasma cutting-torch, initial alignment and anticollision device, collision-prevention device and the igniter of dusting.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a left view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
Fig. 1, shown in Figure 2 comprises: drive motors 1, installing rack 2, nut seat 3, screw mandrel 4, housing 5, travel switch control panel 6, elevating lever 7, guide pad 8, telescopic 9, installed part 10, gathering sill.
Cutting torch lifting mechanism of the present invention, be included in and be set with installing rack 2 in the housing 5, on installing rack 2, be provided with drive motors 1, the output shaft of described drive motors 1 is connected with screw mandrel 4 downwards, in housing 5, be provided with elevating lever 7, be provided with travel switch control panel 6 in elevating lever 7 one sides, the bottom of elevating lever 7 is provided with the cutting torch installed part 10 that stretches out housing 5, in housing 5, be provided with guide pad 8, offer gathering sill on the guide pad 8, described elevating lever 7 is slidingly connected in the gathering sill, is provided with the nut seat 3 with its engagement outside screw mandrel 4, is fixedly connected with elevating lever 7 downwards on described nut seat 3.
Stretch out the resilient telescopic 9 of elevating lever 7 overcoats outside the housing 5.Described guide pad 8 has two, and they present in housing 5 down and be provided with, and the guide pad 8 that is positioned at the bottom is arranged on the base plate of housing 5.Described drive motors 1 is a direct current generator.
The present invention adopts screw mandrel 4 and bearing to be directly installed on the installing rack 2; Nut seat 3 is directly installed on elevating lever 7 tops, and is installed in together on the installing rack 2 with guide pad 8; During installation, must be noted that the cooperation of screw mandrel 4 and nut seat 3, make the cooperation between screw mandrel 4 and the nut seat 3 more smooth and easy, guarantee no stuck phenomenon by rotary screw rod 4 back and forth.Then drive motors 1 is installed on the installing rack 2 by the cooperation between key and the screw mandrel 4; In that the travel switch fixed head 6 that travel switch is housed is contained on the installing rack 2, guarantee that the travel switch up and down that is installed on travel switch control panel 6 can both play position-limiting action, and guarantee to have the stroke of 200mm; Telescopic 9 is being put, and connector 10 is installed on the elevating lever 7; Adorn housing 5 and some other annex at last.
During use, the present invention is contained on the main beam.Elevating mechanism is to drive elevating lever 7 by drive motors 1 by screw mandrel 4, makes coupled cutting torch do the oscilaltion campaign, keeps its suitable distance thereby can make cutting torch and be cut to adjust between workpiece.Because having on main beam can transverse movement, and main frame can carry out lengthwise movement, so just cutting torch can be moved to X, any point is put in the Building Y.The lifting of cutting distance has also realized being cut the adjustment that the steel plate different-thickness requires by computer control.
