Abstract

A snap spring assembling tool comprises a feeding opening, a cone sleeve having an annular cover connected with the back end thereof, a core shaft passing through the annular cover and disposed in the cone sleeve, a notch on one end of the core shaft in the cone sleeve and an elastic unit disposed in the notch in the core shaft. The elastic unit comprises two moveable blocks, two springs, connecting boards and two bolts. The two moveable blocks are oppositely disposed and are respectively provided with slots, the positions of which are corresponding to each other, and a blind hole at two sides of the slot. The two ends of the spring are disposed in the blind holes corresponding to the two moveable blocks. Two bolts are respectively connected with the core shaft after passing through the connecting boards and a slot. One end outside of the cone sleeve is connected with a pressing handle. By using the invention, the manufacturing efficiency for a snap spring assembly is greatly promoted, the working intensity is obviously decreased and the defective products are efficiently decreased.

Description

Snap spring assembling tool
Technical field
The invention belongs to the hand-operated tools of the part assembling that is specially adapted for distortion, relate to a kind of snap spring assembling tool.Be suitable for to do jump ring is installed to special manual instrument in the jump ring groove of part (for example the piston of engine etc.).
Background technology
In the engine production assembling process, jump ring need be installed in the jump ring groove of piston of engine, prior art generally is that the operator is placed into jump ring on the groove earlier, again with changing cutter with in its jump ring groove of packing into.Because jump ring is thin, diameter is relatively large, dynamics is difficult for grasping during operator's hand assembled, and assembling is inconvenient, injures the jump ring groove easily, and efficiency of assembling is very low.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned deficiency of the prior art, and a kind of simple in structure, snap spring assembling tool that efficiency of assembling is high is provided.
Content of the present invention is: a kind of snap spring assembling tool is characterized in that comprising:
The conical sleeve (4) that feeding port (6) are arranged, rear end socket of this conical sleeve (4) or the ring cover that has been threaded (10);
A mandrel (3), this mandrel (3) pass ring cover (10), one section and are positioned at conical sleeve (4), are positioned at mandrel (3) one ends jagged (12) of conical sleeve (4);
Elastic parts in breach (12) that is arranged at mandrel (3), this elastic parts is made of 2 movable blocks (1), 2 springs (2), connecting plate (7) and 2 screws (9); Described 2 movable blocks (1) are oppositely arranged, and the bar hole (13) of position correspondence is arranged respectively and be positioned at the blind hole (8) of bar hole (13) both sides; The two ends of each spring (2) place the corresponding blind hole in position (8) of 2 movable blocks (1) respectively; Described 2 screws (9) pass connecting plate (7) respectively and fixedly connected with described mandrel (3) screw thread in a bar hole (13) back.
In the content of the present invention: the outer end of conical sleeve (4) that is positioned at of described mandrel (3) is fixedly connected with pressure handle (5) by screw (11), uses with convenient.
In the content of the present invention: the front end outer peripheral face of described conical sleeve (4) has been preferably annular concave platform (14), so that jump ring accurately is assembled in the jump ring groove.
Compared with prior art, the present invention has following characteristics and beneficial effect:
(1) adopts the present invention, can simply jump ring be assembled to fast in the jump ring groove, reduce labour intensity, improve the production efficiency of jump ring assembling greatly, can't damage the jump ring groove edge, effectively reduce defective products and produce;
(2) simple in structure, cost is low, makes easily, produces easy to install, practical.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is an embodiment of the invention sectional structure schematic diagram;
Fig. 3 is the left TV structure schematic diagram of Fig. 1.
Among the figure: 1-movable block, 2-spring, 3-mandrel, 4-conical sleeve, 5-pressure handle, 6-feeding port, 7-connecting plate, 8-blind hole, 9-screw, 10-ring cover, 11-screw, 12-breach, 13-bar hole, 14-annular concave platform.
The specific embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of snap spring assembling tool, its structure is formed and is comprised:
The conical sleeve 4 that feeding port 6 is arranged, the rear end socket of this conical sleeve 4 or the ring cover 10 that has been threaded, front end outer peripheral face have annular concave platform 14;
A mandrel 3, this mandrel 3 pass ring cover 10, one section and are positioned at conical sleeve 4, and it is jagged 12 to be positioned at mandrel 3 one ends of conical sleeve 4, is positioned at conical sleeve 4 outer ends and is fixedly connected with pressure handle 5 by screw 11;
Elastic parts in breach 12 that is arranged at mandrel 3, this elastic parts is made of 1,2 springs 2 of 2 movable blocks, connecting plate 7 and 2 screws 9; Described 2 movable blocks 1 are oppositely arranged, and the bar hole 13 of position correspondence is arranged respectively and be positioned at the blind hole 8 of bar hole 13 both sides; The two ends of each spring 2 place the corresponding blind hole 8 in the position of 2 movable blocks 1 respectively, that is: the two ends of a spring 2 place the corresponding blind hole 8 in position of 2 movable blocks 1, the two ends of another spring 2 to place corresponding another blind hole 8 in position of 2 movable blocks 1; Described 2 screws 9 pass connecting plate 7 respectively and fixedly connected with described mandrel 3 screw threads in bar hole 13 backs; 2 movable blocks 1 are under the effect of 2 spring 2 power, along on the inwall that moves radially, abuts against conical sleeve 4 of mandrel 3.
During use, but operator's left hand is held conical sleeve 4; The right hand spurs pressure handle 5, mandrel 3 is moved to ring cover 10 1 ends in conical sleeve 4, stops after breach 12 1 ends of mandrel 3 move past feeding port 6; Jump ring to be installed is inserted in the conical sleeve 4 from feeding port 6; The hole that again 14 1 sections of the annular concave platforms of conical sleeve 4 is placed the need of part (for example the piston of engine etc.) that jump ring is installed; Promoting pressure handle 5, pressure handle 5 drive mandrels 3 and jump ring in conical sleeve 4 moves in conical sleeve 4, the mobile compression spring 2 of movable block 1 in conical sleeve 4, when the front end of jump ring from conical sleeve 4 ejects and be assembled in the jump ring groove of part, promptly finish the assembling of jump ring.
Adopt the present embodiment snap spring assembling tool that jump ring is installed, can enhance productivity greatly, reduce labour intensity, also can effectively reduce defective products and produce.
The invention is not restricted to the foregoing description, content of the present invention is described all can implement and have described good result.
