Abstract
The utility model belongs to a workpiece clamping mechanism which belongs to the mechanical field. The utility model comprises a bracket, a guide rail, wherein a guide block forms a slide fit with the guide rail without separation and a screw rod forms a rotary fit with the guide block. The utility model is characterized in that one side or both sides of the clamping mechanism is (are respectively) provided with a hydraulic gear composed of a hydraulic cylinder and a piston, and a central hole of the piston forms a rotary fit with a shaft journal of the screw rod. The utility model which is operated in double ways of manual and hydraulic work has the advantages of steady workpiece clamping, compact structure, good adjustability, combination of manual operation and hydraulic operation and convenient operation and maintenance. In addition, the utility model can effectively improve the automation level and the operation performance of the complete mechanism.
Description
The utility model belongs to a kind of clamping device of mechanical field, mainly is meant the improvement technical scheme of workpiece grip mechanism in the band sawing machine.
At present the workpiece grip mechanism in the band sawing machine generally has manual method and the two kinds of forms of method of surging, and manually method is that rotation with screw rod drives guide block and moves on guide rail and realize the clamping of workpiece.The method of surging promptly realizes the clamping of workpiece with the motive force of piston in hydraulic cylinder.Manually the method troublesome poeration than the difficult automation degree of equipment that improves, often damages saw band and parts because of chucking power is not enough, and the accident of bringing out produces.And the hydraulic method clamping is subjected to the frequent change of specification of workpieces, and levelling is inconvenience very.
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provide a kind of will be manually and the ingenious workpiece grip mechanism that combines of the mechanism of surging.
Describedly manually surge and use clamping device, comprise support, guide rail, guide block and guide rail do not break away from and are slidingly matched, and screw rod cooperates with the guide block rotation.A side that it is characterized in that clamping device has the hydraulic gear that is made of hydraulic cylinder, piston, and piston center hole does not break away from rotation with a side screw rod axle journal and cooperates.
Describedly manually surge and use clamping device, it is characterized in that the clamping device both sides have the hydraulic gear that is made of hydraulic cylinder, piston, piston center hole does not break away from rotation respectively with both sides screw rod axle journal and cooperates.
This manually surges and uses clamping device, and holding workpiece is firm, compact conformation, and adjustability is good, manually surges and usefulness, and operating maintenance is easy.Owing to the improvement of this clamping device, can improve the automaticity and the service behaviour of complete machine effectively.
Below in conjunction with Figure of description, the utility model is described in further detail, and provide embodiment.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, support 1 is fastening with guide rail 7 end faces, and support 1 does not break away from rotation with left side screw rod 2 and cooperates, and screw rod 2 screws with guide block 6 screw threads, and guide block 6 is preferably turnable activity with jaw iron 3 and cooperates, so that jaw iron 3 surfaces suit as the best with surface of the work.The clamping device right side has the hydraulic gear that is made of hydraulic cylinder 5 and piston 4, and hydraulic cylinder 5 is fastening with guide rail 7 end faces, and piston 4 centre bores do not break away from rotation with right side screw rod 2 axle journals and cooperate.According to the aforementioned techniques scheme, this clamping device can be that the left and right sides all has hydraulic gear, and promptly the clamping device left side also has the hydraulic gear that is made of hydraulic cylinder 5, piston 4, and left side screw rod 2 does not break away from rotation with piston 4 centre bores and cooperates.One side of hydraulic gear is not installed in the above-mentioned clamping device, and guide block and jaw iron can directly be fixed on the guide rail.During work, rotating screw bolt 2 promotes guide block 6 and jaw iron 3 holding workpieces, and piece-holder power is produced by both sides jaw iron, and the chucking power of surging relies on oil supply system to keep, and promotes guide block 6 and jaw iron 3 clamping work pieces by piston 4.
Claims (2)
1, manually surges and use clamping device, comprise support (1), guide rail (7), guide block (6) and guide rail (7) do not break away from and are slidingly matched, screw rod (2) cooperates with guide block (6) rotation, it is characterized in that this clamping device one side has the hydraulic gear that is made of hydraulic cylinder (5), piston (4), piston (4) centre bore does not break away from rotation with side screw rod (a 2) axle journal and cooperates.
2, as claimed in claim 1ly manually surge and use clamping device, it is characterized in that the clamping device both sides have the hydraulic gear that is made of hydraulic cylinder (5), piston (4), piston (4) centre bore does not break away from rotation respectively with both sides screw rod (2) axle journal and cooperates.
