Abstract
The utility model provides a self-adjusting locking clamp, comprising a main bracket, a handle, a pressing block and a replacement spring; wherein, the main bracket and the pressing block realize connection through a rotary shaft in a hinge mode; the replacement spring is arranged in the nip formed by the pressing block and the replacement spring. The utility model is characterized in that the space between the handle and the main bracket is provided with a handle, a rotary shaft movable block, a connecting bracket and a three-link mechanism formed by a compressing spring; besides, the handle realizes connection with the pressing block end through a rotary shaft in a hinge manner. Having scientific design, simple and reasonable structure, and large application range of the component holding, the utility model is able to satisfy the firm component holding with a thickness change between 0.1 to 10 millimeters; and moreover, the component holding provides firm and reliable holding locking, promising a larger holding for thicker component. As the operation turning force of the nip opening or holding for the clamp is basically the same, and the little turning force needed by the clamp operation, the utility model not only provides convenience for using, but improves the operation security.
Description
Technical field
The utility model relates to anchor clamps, especially a kind of self-regulated locking type anchor clamps that are applicable to piece-holder on the electroplating assembly line.
Technical background
At present, electroplating assembly line or do not have on the electrification plating production line, the anchor clamps that adopted, usually by support, be provided with handle briquetting, be arranged on support and become with compression spring set with hinge connecting mechanism between briquetting, forming a briquetting that the folder mouth is provided with handle between briquetting and support relies on the hinge connecting mechanism can be up and down, form between briquetting and support and press from both sides mouth, utilize the compression spring workpiece that enters the folder mouth can be clamped.The anchor clamps of this structure generally can only clamp locked to the workpiece that thickness changes about 3mm among a small circle.When thickness of workpiece difference was excessive, its clamping effect reduced greatly, or folder is not tight, or lock is not dead, in actual the use, the workpiece obscission often takes place.In addition, a kind of movable parallel-moving type anchor clamps are arranged, it is to utilize translation mechanism to cooperate compression spring or extension spring to satisfy the clamping requirement of different-thickness workpiece.This movable parallel-moving type anchor clamps can grip thickness difference variation workpiece greatly.But when thickness of workpiece increased, the folder mouth of anchor clamps is opened the required power that pulls open to be increased greatly, and opening is big more, and it is just big more to pull open power, and the power of pulling is directly proportional with spring force, and this can increase labor intensity of operating personnel and danger undoubtedly.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned anchor clamps, provides a kind of automatic adjustable range big, and the workpiece that can satisfy the different-thickness variation clamps locked self-regulated locking type anchor clamps.
The utility model self-regulated locking type anchor clamps comprise: main support, handle, briquetting and back-moving spring; Be hinged by rotating shaft between main support and briquetting; Described back-moving spring is installed between the folder mouth that briquetting and main support form, and it is characterized in that: be provided with one by handle, rotating shaft movable block between handle and main support, be connected support and compress the three-link mechanism that spring constitutes; Handle is hinged by rotating shaft and briquetting tail end.
The utility model self-regulated locking type design of Clamping Apparatus principle is: utilize to be total to rod principle, three-link mechanism is applied on the anchor clamps, compressing the characteristics that can adjust the connecting rod pivot position under the spring action automatically by three-link mechanism, energy self-locking when anchor clamps folder mouth is opened; Can regulate its clamping force and self-locking voluntarily according to thickness of workpiece when closing.Realize that anchor clamps are to the automatic adjustment of different-thickness workpiece, the goal of the invention of locking.
The utility model self-regulated locking type jig Design science, rational in infrastructure, simple, the piece-holder scope of application is big, can satisfy the firm grip of the workpiece of 0.1～10mm varied in thickness; The clamping locking of workpiece is solid and reliable, and workpiece is thick more, and clamping force is big more.It is basic identical that power is pulled in the folder mouth unlatching of anchor clamps or the operation that clamps, and the power of pulling that fixture operation is required is little, has both made things convenient for use, has improved the safety of operation again.
The concrete structure of this self-regulated locking type anchor clamps is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of self-regulated locking type anchor clamps.
The specific embodiment
Embodiment: can be clear that from Fig. 1 self-regulated locking type anchor clamps are made up of main support 1, briquetting 2, handle 3, back-moving spring 4, the three-link mechanism 5 that is arranged on 1 of handle 3 and main support.Main support 1 middle part is provided with the hinged bearing 6 of a voltage supply piece 2, and briquetting 2 middle part correspondence positions are provided with an axle sleeve 7, and the axle sleeve 7 on the briquetting 2 is erected on the bearing 6 of main support 1, links into an integrated entity by rotating shaft 8.Back-moving spring 4 is installed between the folder mouth of both formations by spring base 9 and the spring base 10 on the main support 1 that is separately positioned on the briquetting 2.Described three-link mechanism 5 is made of handle 3, rotating shaft movable block 11, connection support 12 and compression spring 13.One end of described handle 3 is provided with two as hinged axis hole, an end that connects support 12 is installed in main support 1 middle part by screw 14, its tail end connects handle 3 by rotating shaft movable block 11, connect support 12 and rotating shaft movable block 11, rotating shaft movable block 11 and 3 on handle and be hinged by rotating shaft 15,16 respectively, connect support 12 tail ends and be provided with a screw rod 17 that vertically is set on the main support 1.This screw rod 17 passes from the bottom surface of main support 1, is nested with compression spring 13 on it, and screw rod 17 ends are provided with spring base 18 and adjusting nut 19, can regulate the elastic force of compression spring 13 by adjusting nut 19.Briquetting 2 tail ends are hinged handle 3 by rotating shaft 20.
The operation principle of self-regulated locking type anchor clamps: when handle 3 pulled outward, three-link mechanism 5 interlocks were opened main support 1 and the folder mouth that briquetting 2 constitutes; When handle 3 during toward interior pressures, three-link mechanism 5 interlocks impel the main support 1 and the folder mouth of briquetting 2 formations to close; The elastic force of compression spring 13 is the clamping force of adjustable clamp mouth voluntarily then, to adapt to the firm grip of different-thickness workpiece.Because the rotating shaft movable block 11 at three-link mechanism 5 middle parts can be around itself and the rotating shaft that is connected support 12 15 pin joint left and right sides circular swing motions with rotating shaft 16 hinged ends of handle 3.Two rotating shafts 20,16 of handle 3 ends, when rotating shaft movable block 11 is linearly with the rotating shaft 15 pin joint lines that are connected support 12, be an anchor clamps folder mouthful separation that opens and closes; When rotating shaft 16 pin joints of rotating shaft movable block 11 and handle 3 were flapped toward the left side, the folder mouth was closed; When rotating shaft 16 pin joints of rotating shaft movable block 11 and handle 3 are flapped toward the right side, folder mouthful unlatching.Under the effect of 13 pairs of three-link mechanisms 5 of compression spring, the folder mouth of opening or closing is locked.
