Description
Technical field
The present invention relates to a kind of adjustable lever pin removal.
Background technology
In the machine-building process, often in two part junctions with having the pivot pin 1 of tapering ' locate, when dismounting, just use driver-extractor 2 ' (seeing schematic diagram 1) extract pivot pin 1 ', part separately.In unloading process, can be subjected to the restriction of external environment condition, can only use externally unrestricted occasion, just can use driver-extractor 2 ', but when running into the external environment condition of Figure 12, driver-extractor 2 ' just make and do not used; And, in utilization 2 ' time of driver-extractor, be rely on the motion of tup 3 ' from the bottom up knock handle 4 ' the convex surface place, and the active force that produces makes the power of pivot pin 1 ' up pull out, and that the body mechanics has only the performance of basipetal power to be only is best, this beginning must be in utilization 2 ' time of driver-extractor, and strength will be restricted; Simultaneously, tup 3 ' percussion handle 4 ' the boss place time, the impact that can produce is that the hand that is held in handle 4 ' locate is easy to shake and hinders.For this reason, the driver-extractor 2 ' poor effect of existing use.
Summary of the invention
Do not make power when exist using, shake and hinder hand and be not suitable for the complex external problem of environment easily, the invention provides a kind of body mechanics of meeting and to produce the best use of power, can not shake and hinder hand, increased considerably the adjustable lever pin removal of applicable situation very much for the driver-extractor that solves present use.
Technical scheme of the present invention:
Adjustable lever pin removal, comprise thread head, it is characterized in that: described thread head is a ladder circular shaft structure, the one end is the external thread structure that is used to connect pivot pin, be connected with the adjustable adjustable connecting rod of link position on the end of its other end, the other end of described adjustable connecting rod is hinged with boosting-rod, and the centre of described adjustable connecting rod is connected with the adjustable adjustable support bar of link position, and described thread head, adjustable support bar, boosting-rod are parallel to each other.
Further, the link of described thread head and adjustable connecting rod is provided with the first fixing pivot pin, and described adjustable connecting rod inside is provided with and the first fixing first slippage locating slot that be connected of pivot pin.
Further, described adjustable connecting rod and described adjustable support bar all are flat structures, the plane of described adjustable connecting rod is provided with several second fixing pivot pins, and the inside of described adjustable support bar is provided with and the second fixing second slippage locating slot that be connected of pivot pin.
Further, described adjustable connecting rod is connected with boosting-rod by hinges.
Further, the bottom of described adjustable support bar is a nose circle face.
Technical conceive of the present invention, thread head is the ladder circular shaft, one end is an external screw thread, be used to connect the internal thread hole that is disassembled pivot pin, an end is flat shape, and head is provided with the first fixing pivot pin, can be used for connecting adjustable connecting rod, and the position of the first slippage locating slot by the adjustable connecting rod of conversion, promptly can change and adapt to adjustable support bar and thread head between distance, reach the purpose of adjustable range; Adjustable connecting rod profile is flat, there is the first slippage locating slot inside, several second fixing pivot pins are arranged on the plane, be used to connect adjustable support bar, and slippage in can the second slippage locating slot in adjustable support bar, play the response position (playing the effect heightened) that changes adjustable support bar, the other end has an endoporus, is connected with boosting-rod by hinges; Adjustable support bar profile is flat, there is the second slippage locating slot inside, on the second slippage locating slot and the adjustable connecting rod second fixedly pivot pin is connected, by position in the second slippage locating slot in the adjustable support bar of conversion, can regulate the response position of adjustable connecting rod and adjustable support bar, when adapting to work, the affected situation of support works table top height; And adjustable support bar can be from adjustable connecting rod second fixedly shift out the pivot pin, put into another the second fixing pivot pin on the adjustable connecting rod, play too change and adapt to adjustable support bar and thread head between distance, reach the method for adjustable range, the bottom is a nose circle face, purpose is in order to increase the contact compression area, and plays stabilization; Boosting-rod is connected with adjustable connecting rod by hinges, and can do the rotation of certain angle around hinges, plays the effect of adjusting angle.
Principle of the present invention is the same substantially with lever principle, adjustable support bar can be regarded as a fulcrum, adjustable connecting rod can be regarded lever as, when boosting-rod one end adds down a power, the other end at adjustable connecting rod will produce an active force up, this active force up makes thread head generation displacement up, and pivot pin is transferred in the locating hole.
The use of adjustable lever pin removal is as follows:
1, in the internal thread hole in the location axle pin in the thread head screw-in equipment;
2, the first slippage locating slot that adapts in the adjustable connecting rod is inserted the first fixing pivot pin of the first end of screw thread, connected;
3, the second slippage locating slot that adapts in the adjustable support bar is inserted fixedly pivot pin of second on the adjustable connecting rod, connected;
4, boosting-rod is adjusted to corresponding vertical angle;
5, grasp boosting-rod, knock the boosting-rod upper end, make boosting-rod generation displacement down with hand hammer;
6, power makes other end generation one active force up at adjustable connecting rod by the transmission of adjustable connecting rod, makes thread head generation displacement up, thereby pivot pin is extracted in the locating hole.
Effect intentionally of the present invention:
(1) percussion power is from top to bottom, meets the body mechanics and produces best active force, and is more convenient laborsaving when allowing the user use;
(2) because power is not to act directly on the thread head, and the place of shaking hands can not produce bigger shaking force, hand can be not injured;
(3) adjustable height of the distance of adjustable support bar and thread head and adjustable support bar makes the present invention not be subjected to the influence of work top height;
(4) simple and reasonable, increased considerably very much applicable situation.
