Abstract
The utility model relates to an elastic pin locking structure, which comprises an elastic pin, a supporting block, a spring and a clamp body, wherein the supporting block is fixed on the clamp body, the elastic pin is matched with the supporting block in a sliding way and stretches out from one end of the supporting block, a spring installation hole is arranged in the clamp body below the supporting block, the spring is installed in the spring installation hole and props against the elastic pin, the other end of the elastic pin penetrates through the spring and stretches out of the clamp body, the clamp body is fixedly provided with a hydraulic floating supporting cylinder, and a piston rod of the hydraulic floating supporting cylinder props against the other end of the elastic pin. Due to the adoption of the elastic pin locking structure, after a component is positioned by the elastic pin, the hydraulic floating supporting cylinder applies an axial compression force onto the elastic pin so as to lock the elastic pin, the elastic pin can be prevented from having axial displacement in the machining process of the component, precision in positioning of the component can be guaranteed, and the rejection rate of the component can be reduced.
Description
Technical field
The utility model relates to the frock clamp of machinery industry, specifically a kind of resilient key latch-up structure.
Background technology
Along with the continuous progress of society, machinery manufacturing industry is in rapidly development, and people are also constantly improving the required precision of machined part.Having higher requirement in the location in process that improves constantly workpiece of machined part precision, makes the frock clamp positioning requirements more accurate.
Resilient key location is as first operation locate mode (blank location) commonly used in part processing, and the machining accuracy that its positioning accuracy directly has influence on the back all process steps is the scrappage of machined part even.In prior art; the not high phenomenon of reliability of positioning often can appear in resilient key, and its reason is that part can produce vibrations in mechanical processing process, when the suffered axial force of resilient key during greater than spring force; part can produce displacement, has a strong impact on the positioning accuracy of part processing.
Summary of the invention
The utility model provides a kind of resilient key latch-up structure for the problems referred to above, and this latch-up structure can prevent the axial displacement of resilient key effectively, guarantees the machining accuracy of machined part.
according to the technical solution of the utility model: a kind of resilient key latch-up structure, comprise resilient key, rest pad, spring and clamp body, described rest pad is fixed on described clamp body, described resilient key is slidably fitted in described rest pad and stretches out from an end of described rest pad, have spring mounting hole in the described clamp body of described rest pad below, described spring fitting is in described spring mounting hole and be resisted against on described resilient key, the other end of described resilient key passes described spring and stretches out described clamp body, be fixed with hydraulic pressure over draft cylinder on described clamp body, the piston rod of described hydraulic pressure over draft cylinder is resisted against on the other end of described resilient key.
Have the over draft installation cavity in described clamp body, described hydraulic pressure over draft cylinder is arranged in described over draft installation cavity.
Described hydraulic pressure over draft cylinder is arranged on the over draft mount pad, and described over draft mount pad is fixed on described clamp body.
Between described rest pad and described clamp body, the adjustment pad is installed.
Be provided with axially extended chute on the sidewall of described resilient key, the limited location screw that is threaded on described rest pad, the tail end of described stop screw stretches in described chute.
Technique effect of the present utility model is: the utility model is after resilient key is completed part location work, by hydraulic pressure over draft cylinder, resilient key is applied axial thrust, thereby locking elastic pin, prevent that axial displacement from appearring in part process Elastic pin, guarantee the positioning accuracy of part, reduce the scrappage of part.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise resilient key 1, rest pad 2, adjust pad 3, spring 4, hydraulic pressure over draft cylinder 5, over draft mount pad 6, clamp body 7, stop screw 8, spring mounting hole 9, over draft installation cavity 10, chute 11 etc.
As shown in Figure 1, the utility model is a kind of resilient key latch-up structure, comprises resilient key 1, rest pad 2, spring 4 and clamp body 7, and rest pad 2 is fixed in groove on clamp body 7, be equipped with between the bottom portion of groove of rest pad 2 and clamp body 7 and adjust pad 3, play corrective action.
Resilient key 1 is slidably fitted in rest pad 2 and stretches out from an end of rest pad 2, have spring mounting hole 9 in the clamp body 7 of rest pad 2 belows, spring 4 is arranged in spring mounting hole 9 and is resisted against on resilient key 1, and the other end of resilient key 1 passes spring 4 and stretches out clamp body 7.Be fixed with hydraulic pressure over draft cylinder 5 on clamp body 7, the piston rod of hydraulic pressure over draft cylinder 5 is resisted against on the other end of resilient key 1.
At the interior over draft installation cavity 10 that preferably has of clamp body 7, hydraulic pressure over draft cylinder 5 is arranged in over draft installation cavity 10.Hydraulic pressure over draft cylinder 5 is arranged on over draft mount pad 6, and over draft mount pad 6 is fixed on clamp body 7.Over draft mount pad 6 provides hydraulic oil for hydraulic pressure over draft cylinder 5.
