Abstract
The utility model discloses a stroke adjusting device, which relates to an auxiliary device for controlling mechanism stroke, particularly used for controlling piston stroke of a rubber tube crimping machine and further adjusting crimping quantity of the rubber tube crimping machine. The stroke adjusting device is characterized in that the whole device comprises a screw rod 5, an adjusting screw nut 4, a fine adjustment spring 3, an adjusting seat 2, an adjusting sleeve 1 and a screw 6; the screw rod 5 and the adjusting sleeve 1 are integrally fixed through the screw 6; when the adjusting sleeve 1 is rotated, the screw rod 5 rotates along with the adjusting sleeve 1; threads on the adjusting screw nut 4 match with threads on the screw rod 5; the length of an extending end of the screw rod 5 is adjusted by rotating the screw rod 5; and the adjustment spring 3 is installed between the adjusting screw nut 4 and the adjusting seat 2 so as to realize the functions of positioning and automatically resetting the adjusting screw nut 4 and perform self-protection function. The whole device is fixed to the end surface of a crimping head 8 of the rubber tube crimping machine through the adjusting seat 2; the device can control the piston stroke and further adjust the crimping quantity of the rubber tube crimping machine; the screw rod 5 matches with the adjusting screw nut 4 through trapezoidal threads; the screw rod 5 moves circumferentially to lead the adjusting screw nut 4 to move axially; the thread pitch of the trapezoidal threads is 2mm or 3mm; and the trapezoidal threads match with a crimping machine with a die holder inclined surface angle of 15 degrees or 20 degrees. The stroke adjusting device has simple structure and high control accuracy, can realize self-protection and is not easily damaged.
Description
Technical field:
The utility model relates to a kind of complementary device of controlling organization stroke, and be particularly useful for sebific duct and withhold machine equipment, the control piston stroke, and then regulate sebific duct and withhold the stroke adjusting device of the amount of withholding of machine.
Background technology:
At present, sebific duct is withheld the adjusting of the amount of withholding of machine, adopts sensor control circuit more.Its advantage is the accuracy height, be easy to realize, but its cost is higher, and circuit complexity, reliability are not high, break down easily.Also have and adopt mechanical device to regulate the amount of withholding, but its accuracy is not high, and do not have automatic safety device, in case break down, device is damaged easily.
Summary of the invention:
The purpose of this utility model: overcome the sensor control circuit complexity, reliability is low, the accuracy of mechanical device is not high, be easy to shortcomings such as damage and provide a kind of simple in structure, the control accuracy height, and non-damageable stroke adjusting device, satisfy the requirement of withholding machine, improve the service behaviour of withholding machine.
The utility model stroke adjusting device is made up of screw rod 5, adjusting nut 4, fine setting spring 3, adjustment seat 2, regulating sleeve 1, screw 6.Screw rod 5 and regulating sleeve 1 usefulness screw 6 are fixed together, and when rotary regulating sleeve 1, screw rod 5 can rotate together; The threaded engagement of adjusting nut 4 on threaded and screw rod 5, the length of rotary screw 5 adjusting screw(rod)s 5 external parts; Regulating spring 3 is installed between adjusting nut 4 and the adjustment seat 2, realizes the location of adjusting nut 4 and automatically replies effect, and play the self-protection effect.Screw rod 5 and adjusting nut 4 cooperate by trapezoidal thread, and screw rod 5 circumferential movement make adjusting nut 4 produce axially-movable.Trapezoidal thread is that pitch is 2mm or 3mm, with the die holder bevel angle be that the machine of withholding of 15 ° or 20 ° is used.Whole device is fixed on 8 the end face withheld that sebific duct is withheld machine by adjustment seat 2, the control piston stroke, and then regulate the amount of withholding that sebific duct is withheld machine.
Advantage of the present utility model and good effect demonstrate fully into:
1. this apparatus structure is simple, and is easy-to-use, satisfies the requirement of withholding machine, the control accuracy height, and operation is stable.
2. owing to adopt the suitable pitch of 2mm or 3mm, make the axial stroke of adjusting device and withhold control accuracy height between the machine opening degree.
3. between adjusting nut 4 and the adjustment seat 2 regulating spring 3 is housed, has realized the axially-movable of screw rod, protect whole device, not fragile.
