The lower end of the C-shaped clamping claw is designed to be an adjustable bolt ejection column. The sliding and automatic clamping device has the advantages of being convenient to use, practical, simple in operation, and low in using cost when the sliding and automatic clamping device is used for clamping workpieces.

Description

The slip automatic clamping device

Technical field

The utility model relates to a kind of anchor clamps, is specifically related to a kind of slip automatic clamping device.

Background technology

Anchor clamps are important process equipments indispensable in the machinery manufacturing industry, can guarantee mechanical processing quality, enhance productivity, reduce production costs, reduce labor intensity.

The kind of anchor clamps can be designed to various at workpiece kind, application target, environment for use etc., present stage, China's machinery manufacturing industry is taken strength as the leading factor with medium-sized and small enterprises, in these enterprises, employed generally can not be electrified or the full-automatic expensive anchor clamps of high-tech, nearly all use all be manual anchor clamps, at these type of anchor clamps, have the following deficiency: the manual anchor clamps that 1, do not have relative automation at present; 2, common anchor clamps are one-body molded, the part replacement inconvenience.

The utility model content

The technical problems to be solved in the utility model provides a kind of convenient and practical, and is simple to operate, the slip automatic clamping device of low cost of manufacture.

In order to solve the problems of the technologies described above, the utility model provides a kind of slip automatic clamping device, include pedestal, the handle as force application apparatus, lower elbow lever, upper elbow lever, C clamp pawl and be connected guide post on the pedestal, wherein, lower elbow lever one end is fixedlyed connected with 90 degree with handle, its tie point is hinged on the pedestal, and an end of the other end and upper elbow lever is hinged, and the other end of upper elbow lever and C clamp pawl are hinged; Described C clamp pawl has upper and lower freedom of motion under the guide post constraint, be provided with stage clip between the upper end of described C clamp pawl and guide post, and the two ends up and down of described C clamp pawl is U-shaped, and wherein lower end is set to adjustable bolt fore-set; Can insert a spacing saddle on the pedestal of below, described C clamp pawl termination, the pin joint below of described C clamp pawl and upper elbow lever is provided with the spacer pin of restriction two toggle link range of movement.

This slip automatic clamping device is by the self-holding principle of stage clip, link mechanism by drive end promotes C clamp pawl extruding stage clip, and the driven end that the C clamp pawl is used for clamping opens, and puts into workpiece, discharging drive end, the C clamp pawl is subjected to the extruding of spring Hui Li and workpiece is clamped.

Adopt the slip automatic clamping device of technique scheme to have following advantage: 1, owing between C clamp pawl and the guide post upper end stage clip is installed, so need the artificial application of force when equipment in use only unclamps clamp jaw, what lean on fully during clamping is the elastic force of stage clip and need not manpower, therefore the general relatively anchor clamps of this slip automatic clamping device can be done the merit of half less, and are time saving and energy saving; 2, because C clamp pawl lower end is set to adjustable bolt fore-set, can regulate length according to tool sizes on the one hand, on the other hand, the C clamp pawl can wear and tear very fast in clamping process, removable fore-set can be saved cost, so the use cost of this slip automatic clamping device is lower.

As preferred version, consider that a little Influence of Displacement operating accuracies may take place workpiece in clamping process, so can limit the position of workpiece by groove or projection, and often the saddle of place work piece can wear and tear very fast, if the integrated words of saddle and pedestal can increase the device fabrication cost, therefore can insert a spacing saddle on the pedestal of below, described C clamp pawl termination.

As preferred version, consider the handle overexertion, upper and lower two toggle link angles surpass the 180 degree meeting anti-driving forces of generation and are inconvenient to use, so should make the movement angle of two toggle links be not more than 180 degree, can adopt and forbid that against toggle link it continues the method for motion on one side, therefore the pin joint of described C clamp pawl and upper elbow lever below is provided with the spacer pin of restriction two toggle link range of movement.

As preferred version, consider that handle will drive the motion of lower elbow lever, handle is directly controlled the direction of lower elbow lever, handle before not clamping has fully surpassed base plane if the angle that handle is connected with lower elbow lever is crossed conference, and angle too small can cause rotation inconvenient, this angle 90 is best, so the angle that handle is fixedlyed connected with lower elbow lever is 90 degree.

Description of drawings

Fig. 1 is the slide main TV structure schematic diagram of automatic clamping device of the utility model embodiment.

The specific embodiment

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

As shown in Figure 1, the utility model provides a kind of slip automatic clamping device, include pedestal 6, the handle 10 as force application apparatus, lower elbow lever 9, upper elbow lever 8, C clamp pawl 3 and be connected guide post 2 on the pedestal, wherein, lower elbow lever 9 one ends are fixedlyed connected with 90 degree with handle 10, its tie point is hinged on the pedestal 6, and an end of the other end and upper elbow lever 8 is hinged, and the other end of upper elbow lever 8 and C clamp pawl 3 are hinged; Described C clamp pawl 3 has upper and lower freedom of motion under guide post 2 constraints, be provided with stage clip 1 between the upper end of described C clamp pawl 3 and guide post 2, and the two ends up and down of described C clamp pawl 3 is U-shaped, and wherein lower end is set to adjustable bolt fore-set 4; Can insert a spacing saddle 5 on the pedestal 6 of below, described C clamp pawl 3 terminations, described C clamp pawl 3 is provided with a spacer pin 7 that limits two toggle link range of movement with the pin joint below of upper elbow lever 8.

Concrete using method is: the slip automatic clamping device is placed workbench, by fixing hole 11 this clamping device is fixed on the workbench, turning handle 10 makes progress, angle between lower elbow lever 9 and the upper elbow lever 8 becomes 180 degree, C clamp pawl 3 is boosted by upper elbow lever 8, and open the termination, puts into workpiece, release lever 10 then, and C clamp pawl 3 is subjected to the extruding of 1 time power of stage clip and workpiece is clamped automatically.

Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; should be considered as protection domain of the present utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
