Description
Technical field
The present invention relates to a kind of pin removal, particularly a kind of quiet pin removal.
Background technology
The tapped pin of the general employing of pin that often needs the dismounting position on machine, the mould, when keeping in repair, extracts machine tool the method for this pin, what more generally adopt at present is the impact type pin removal, namely in screwed hole, be screwed into a screw, utilize the impulsive force of the jump bit that is overlapping on the pin removal bar, extract pin; The method has following shortcoming: 1. jump bit can produce noise in the process that impacts, and there is noise pollution at the production operation scene; 2. vibration be can produce in the impact process, machine, other position of mould, the particularly precision of ultraprecise part affected; 3. impact shock easily makes surface of the work contact other object and produces the scuffing of damaging, and affects machine, die surface quality; 4. impact shock has and makes broken screw stay risk in the pin hole, affects extracting of pin.
Summary of the invention
For the deficiency that exists on the prior art, the invention provides a kind of simple in structure, easy to use, and noiselessness, friction, firmly economize, stable working, pull out the quiet pin removal that uses with the internal thread pin when being particularly suitable for the assembling of precision optical machinery, mould and maintenance.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of quiet pin removal, comprise the pin removal main body, be provided with sliding shoe in the described pin removal main body, sliding shoe can be along mobile in the pin removal main body, sliding shoe is arranged in the pin removal main body by lower cover, pin removal main body and sliding shoe are interspersed with screw rod, there is a hole position in the middle of on one end face of pin removal main body, be used for passing screw rod, sliding shoe is provided with connecting screw, and connecting screw is passed lower cover and is connected with pin, and pin is threaded pin to be pulled out, sliding shoe and lower cover are detachable, so can change easily.
Further, described lower cover is fixed on the pin removal main body by the first screw, and respectively there is an offset on top lower two sides, the U-lag edge of pin removal main body; By both sides a screwed hole is arranged respectively on the pin removal body openings direction end face, this screwed hole and the first screw coupling are used for fixedly lower cover.
Further, described the first screw is ware type screw, is used for the locking lower cover.
Further, the link position of described screw rod and pin removal main body is provided with pad.
Further, the centre position of described pad is provided with draw-in groove, and draw-in groove is stuck on the screw rod.
Further, described draw-in groove is U-lag.
Further, described pin removal main body is provided with backing pin, and backing pin is the pad backing pin.
Further, described backing pin is straight pin.
Further, described pin removal main body is provided with the second screw, and the second screw is spacer screw, and pad is connected with the second screw.
Further, described pin removal main body is provided with U-lag, and sliding shoe places U-lag.
Further, described lower cover is a cuboid, and lower cover is provided with rectangular channel, and connecting screw places rectangular channel, and this rectangular channel is used for passing through pin.
Adopt the quiet pin removal of technique scheme, owing to being provided with sliding shoe in the described pin removal main body, sliding shoe can be along mobile in the pin removal main body, sliding shoe is arranged in the pin removal main body by lower cover, pin removal main body and sliding shoe are interspersed with screw rod, there is a hole position in the middle of on one end face of pin removal main body, be used for passing screw rod, sliding shoe is provided with connecting screw, connecting screw is passed lower cover and is connected with pin, pin is threaded pin to be pulled out, sliding shoe and lower cover are detachable, so this quiet pin removal noiselessness, friction, firmly economize, stable working, sliding shoe and lower cover are changed convenient, wide accommodation is particularly suitable for precision optical machinery, pulling out band internal thread pin when the assembling of mould and maintenance uses.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the quiet pin removal of the present invention.
Fig. 2 is the exploded view of the quiet pin removal of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Such as Fig. 1 and shown in Figure 2, a kind of quiet pin removal, comprise pin removal main body 6, be provided with sliding shoe 5 in the pin removal main body 6, sliding shoe 5 can be along the 6 interior movements of pin removal main body, sliding shoe 5 is arranged in the pin removal main body 6 by lower cover 3, pin removal main body 6 is interspersed with screw rod 10 with sliding shoe 5, and there is a hole middle position on the end face of pin removal main body 6, is used for passing screw rod 10, the end outer surface of screw rod 10 is provided with screw, be hexagon socket head cap screw, sliding shoe 5 is provided with connecting screw 4, and connecting screw 4 is passed lower cover 3 and is connected with pin 1, pin 1 is threaded pin to be pulled out, sliding shoe 5 is a cuboid, and groove is respectively arranged one on its two sides, can cooperate with U-lag 61 positions of pin removal main body 6, there is a tapped through hole at the one end center, can cooperate with screw rod 10, it has a T shape blind slot by on the other end upper surface, is used for cooperating with connecting screw 4, sliding shoe 5 is detachable with lower cover 3, so can change easily.
The profile of the quiet pin removal of the present invention is rectangle, during work, the connecting screw 4 of at first in the screwed hole of tapped pin 1 to be pulled out, screwing on, assemble pin removal, the head of connecting screw 4 is enclosed within the groove of sliding shoe 5, screw rod 10 is screwed in the screwed hole of sliding shoe 5, when the major part of screw rod 10 and the gap between the pin removal main body 6 are larger, can fill up the pad 7 of suitable thickness, turn screw rod 10, sliding shoe 5 moves upward, and drives the connecting screw 4 that links to each other with pin 1, thereby extracts pin; If this quiet pin removal cooperates electric inner hexagon spanner, then pull inner hexagon spanner efficient than hand higher.Because different pins 1 screwed hole specification is different, therefore need the connecting screw 4 and sliding shoe 5 of standby several specifications.
