Abstract

The utility model provides a hand-operated pressing machine. An operating platform is mounted on a machine body and then positioned by a positioning pin and fastened by a bolt; a shaft sleeve is welded on the machine body, an end sleeve is mounted on the shaft sleeve, and a gear shaft is mounted inside the shaft sleeve and the end sleeve; a retaining ring and a screw nail II are mounted on the gear shaft, and a handle is mounted on the gear shaft; a screw rod, a locking pin and a butterfly nut are connected into a whole; a baffle plate is fixed on the machine body through a screw nail I; and a rack press rod is mounted inside a sliding chute formed by the baffle plate and the machine body, the rack press rod is engaged with the gear shaft, and the screw rod is mounted on the baffle plate. The utility model has the advantages that the hand-operated pressing machine allows one operator to complete the operation of assembling or disassembling a work piece with springs, is easy to operate and can effectively control the compression stroke of the springs, thereby improving the assembly quality of the work piece and saving labor; and the hand-operated pressing machine is safe to operate and has lower probability of damaging the work piece.

Description

Hand press

Technical field: when the invention is civil aviaton's servicing center maintenance aircraft components, the equipment of assembling and dismounting spring.

Background technology: generally speaking, spring is in the inside of some part cavitys when assembling, in assembling process, often need spring is compressed under certain state, assemble other part again, make spring be in compressive state always, maintain outside elastic force, concerning the lower spring of some coefficients of stiffiness, assembling and dismounting are not what be difficult to, but for the very high spring of the coefficient of stiffiness, it is just very difficult to want assembling and dismounting, when many civil aviatons install and remove such spring in the servicing center, need on some hydraulic press, carry out, link to each other with special-purpose mold by forcing press, spring is compressed, thereby carry out the assembling of aircraft components, still, forcing press power ratio in general is bigger, generally all more than several tons, extremely difficult for the compression travel of control spring, to control badly sometimes, often that some are relevant airplane parts cause badly damaged, thereby cause a large amount of losses, in addition, the operator there is very high danger, and, the assembling of some parts, need special messenger's operating pressure machine, need the special messenger to assemble, cooperate and tacit agreement extremely just can finish assembling.

Summary of the invention: the purpose of the invention provides a kind of assembling that has spring members or hand press of field-strip can a people finished, the purpose of the invention is to realize by following technical scheme: hand press is characterized in that being made of body, operating platform, tooth bar depression bar, handle, screw I, gear shaft, axle sleeve, bolt, baffle plate, screw rod, locking pin, wing nut, termination point casing, back-up ring, screw II and alignment pin; The body upper end is shaped on the hole of installation axle sleeve and the screwed hole of mounting screw I, gear shaft one end is made gear, make the screwed hole of cartridge screw II on gear face, the other end is shaped on the through hole that handle is installed, and is shaped on the through hole of mounting screw I on the baffle plate and the screw flight hole is installed; Operating platform is installed on the body, with the alignment pin location, uses bolted, axle sleeve is welded on the body upper end, termination point casing is contained on the axle sleeve, gear shaft is contained in axle sleeve and the termination point casing, back-up ring and screw II are contained on the gear shaft, handle is contained on the gear shaft, screw rod, locking pin and wing nut are linked into an integrated entity, baffle plate is fixed on the body with screw I, the tooth bar depression bar is contained in the sliding tray of baffle plate and body formation, tooth bar depression bar and gear shaft engagement are contained in screw rod on the baffle plate.

The advantage of the invention: a people can finish assembling or the field-strip that has spring members, and is simple to operate, the compression travel of control spring well, thus improved the assembly quality of parts, saved manpower; Handling safety, not fragile parts.

Description of drawings:

Fig. 1 is the hand press structural representation;

Fig. 2 is the schematic top plan view of Fig. 1.

Among the figure: 1, body 2, operating platform 3, tooth bar depression bar 4, handle 5, screw I 6, gear shaft 7, axle sleeve 8, bolt 9, baffle plate 10, screw rod 11, locking pin 12, wing nut 13, termination point casing 14, back-up ring 15, screw II 16, alignment pin

The specific embodiment: hand press is characterized in that being made of body, operating platform, tooth bar depression bar, handle, screw I, gear shaft, axle sleeve, bolt, baffle plate, screw rod, locking pin, wing nut, termination point casing, back-up ring, screw II and alignment pin; The body upper end is shaped on the hole of installation axle sleeve and the screwed hole of mounting screw I, gear shaft one end is made gear, make the screwed hole of cartridge screw II on gear face, the other end is shaped on the through hole that handle is installed, and is shaped on the through hole of mounting screw I on the baffle plate and the screw flight hole is installed; Operating platform is installed on the body, locate with alignment pin, use bolted, axle sleeve is welded on the body upper end, termination point casing is contained on the axle sleeve, termination point casing and axle sleeve interference fit are contained in gear shaft in axle sleeve and the termination point casing, gear shaft and axle sleeve and termination point casing matched in clearance, back-up ring and screw II are contained on the gear shaft, play the effect of gear shaft axial location, handle is contained on the gear shaft, handle cooperates with via clearance on the gear shaft, a spheroid is respectively adorned at the handle two ends, handle can be gone here and there and be moved, and prevents that handle from coming off from gear shaft, with screw rod, locking pin and wing nut link into an integrated entity, baffle plate is fixed on the body with screw I, the tooth bar depression bar is contained in the sliding tray of baffle plate and body formation, baffle plate is positioned at the restriction of tooth bar depression bar in the slip and slides, tooth bar depression bar and gear shaft engagement, when gear shaft rotates, drive the tooth bar depression bar and move up and down, screw rod is contained on the baffle plate fastening tooth bar depression bar.

Concrete operations explanation: according to the size of assembly parts, turning handle is adjusted the position of tooth bar depression bar, choose corresponding former mold, mold links to each other with the tooth bar depression bar, spring is packed in the part cavity that will assemble, be placed on the operating platform, left hand is held the part that will assemble, and it is relative with the mold center to adjust the position; Right hand turning handle is adjusted tooth bar depression bar holddown spring, when spring is compressed to the state of requirement, unclamps left hand and removes to turn wing nut, thereby screw rod holds out against the tooth bar depression bar, makes the tooth bar depression bar be fixed on current location, at this moment, both hands all can unclamp, carry out the assembling of other part, after assembling was finished, the right hand was held handle, left hand turns wing nut and unclamps the tooth bar depression bar is locked, slowly turning handle lifting rack depression bar takes off the part that is assembled, and finishes assembling; Dismounting is during spring or during the assembling spring, and mode of operation is identical with above-mentioned program.
