Description
Technical field
The present invention relates to a kind of multiple position press clamping protection device, the clamping protection device that uses on particularly a kind of multiple position press.Belong to the press technical field.
Background technology
In the use of transfer press lathe; balladeur train stroke defect in the feed system appears through regular meeting; perhaps the part plug is in balladeur train; or meet operative employee, instrument etc., cause the undesired increase of the resistance of motion, owing to there is not clamping protection device; so when lathe runs into above situation; will continue operation, this will make lathe damage easily, simultaneously life injury accident, device security accident might take place.At present, on multiple position press, the significance level of clamping does not also cause enough attention, so, all there is not this clamping protection device on the general multiple position press.
Summary of the invention
The objective of the invention is to: the clamping protection device that uses on a kind of multiple position press is provided; it utilizes the friction of arc surface between fixed block and the sliding shoe; set the protection of material folding system by the reduction length of adjusting spring; if occur the balladeur train stroke defect in the feed system; or the part plug is in balladeur train, and when causing the undesired increase of resistance, arc surface is just thrown off; the switch contact impact switch, system alarm is also shut down.
Solving the technical scheme that its technical problem adopts is: the clamping protection device that uses on a kind of multiple position press, it is characterized in that it comprises protection piece, base, screw rod, regulating spring, nut, pad, movable block, the switch contact that is connected with protected mechanism by screw; Make screwed hole on the face of cylinder of described protection piece upper end, the right side makes arc-shaped slot, makes switch contact on the front end face of right side, and the lower end keeps flat on the upper surface of base; The boss of described base left end contacts with protection piece left side, and the bottom makes the lateral step hole; Screw rod is installed in the described stepped hole, and its cylindrical screw head and circular hole are connected; Regulating spring is sleeved on the screw rod; Described movable block upper end make with the protection piece in the arc surface that is complementary of arc-shaped slot and be adjacent to the arc-shaped slot of protection piece, the circle hole sleeve of lower end is contained on the screw rod, and pad and nut are installed on the screw rod of movable block outer end.
Beneficial effect: owing to adopted such scheme, set the protection of clamping system, applied range by the reduction length of regulating spring; Movable block contacts with the fixed block arc surface, and when the system motion resistance was provided with above clamping, movable block moved outward, and reflection is protected reliably rapidly; Simple in structure, Installation and Debugging are convenient.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Shown in the figure: 1, protection piece; 2, base; 3, screw rod; 4, regulating spring; 5, nut; 6, pad; 7, movable block; 8, switch contact.
The specific embodiment
As the clamping protection device that uses on Fig. 1, Fig. 2, a kind of multiple position press shown in Figure 3, it comprises protection piece (1), base (2), screw rod (3), regulating spring (4), nut (5), compressing tablet (6), movable block (7), the switch contact (8) that is connected with protected structure by screw; Make screwed hole on the face of cylinder of described protection piece (1) upper end, the right side makes arc-shaped slot, makes switch contact (8) on the front end face of right side, and the lower end keeps flat on the upper surface of base (2); The boss of described base (2) left end contacts with protection piece (1) left side, and the bottom makes the lateral step hole; Screw rod (3) is installed in the described stepped hole, and its cylindrical screw head and circular hole are connected; Regulating spring (4) is sleeved on the screw rod (3); Described movable block (7) upper end make with protection piece (1) in the arc surface that is complementary of arc-shaped slot and be adjacent to the arc-shaped slot of protection piece (1); the circle hole sleeve of lower end is contained on the screw rod (3), and the screw rod (3) of movable block (7) outer end is gone up pad (6) and nut (5) are installed.
As Fig. 1, Fig. 2, shown in Figure 3, base (2) contacts by arc surface with movable block (7), and contact-making surface connects greatly, frictional force is big, is not obstructed when both break away from.
As shown in Figure 1, adjust the protection numerical value of clamping force, can be suitable for the clamping force protection of different anchor clamps, applied range by the reduction length of screw rod (3), nut (5), regulating spring (4).When clamping force exceeds when pre-seting, the protection piece moves right, and switch contact (8) is run into the switch that is installed on the lathe, and alarm equipment alarm is shut down simultaneously.Be swift in response, install reliable.
