Pneumatic boost pressure bench vice
Technical field
The utility model belongs to machining auxiliary equipment field, specifically is exactly a kind of pneumatic boost pressure bench vice for the automatically quick clamping work pieces of bench work process.
Background technology
In mechanical processing process, often need be fixed on workpiece to be processed on the anchor clamps and handle, when especially carrying out bench work, need be piece-holder after on the bench vice, by the technical staff to the workpiece processing of polishing, at present in the factory floor, pincers worker generally all is manual clamping with bench vice, at first the retaining part of bench vice is opened, then workpiece to be processed is placed on bench vice and clamps, with file workpiece is processed at last.
This traditional pincers worker is with bench vice operation inconvenience, can not better controlled for the big person of low position of power, and need increase working strength of workers than great strength during clamping work pieces.Along with the quickening of industrial production rhythm, traditional screw thread bench vice has not caught up with industrial demand, and operating efficiency is lower, and the screw thread transmission can't realize clamping fast and unclamping.
The utility model content
The bench vice of using at pincers worker in the existing mechanical process all is with manually clamping, the labor intensive material resources, strengthened working strength of workers, and manually clamp speeds is slower, influence production and processing efficient, the solution that the utility model provides is to have manual clamping to be transformed on brave bench vice to start clamping, reduced the clamping force of action need, has shortened to clamp and has installed the time that needs.
Technical scheme
In order to solve above-mentioned technical barrier, the utility model designs a kind of pneumatic boost pressure bench vice, and it comprises the bench vice assembly, it is characterized in that: on the described bench vice assembly pneumatic cylinder assembly is installed.
Further, described bench vice assembly comprises the chassis, rotating disk is housed on the chassis, the jaw mount pad is contained on the rotating disk, regular jaw is contained on the jaw mount pad, and jaw mount pad inner chamber has guide runner, and guide rail is housed in the guide runner, moving jaw is installed on the guide rail, and moving jaw can slide along guide runner with guide rail;
Described pneumatic cylinder assembly comprises pneumatic cylinder, and the screw rod of pneumatic cylinder is connected with guide rail, and pneumatic cylinder is contained on the fixed head, and fixed head is fixedly mounted on the rotating disk.
Further, described jaw mount pad is installed on the rotating disk by screw and pin.
Further, have pin hole on the described chassis.
Further, described guide rail stretches out guide runner one end baffle plate is housed.
Beneficial effect
Pneumatic boost pressure bench vice can provide the clamping force clamping work pieces by pneumatic shuttle, discarded and adopted traditional hand screw rotating clamp clamping of workpieces, as long as the staff opens valve, bench vice just can clamp automatically, and the power that pneumatic means provides can be not excessive yet, can avoid bad workpiece clamp.The utility model both can alleviate workman labour, shortened workpiece and clamped the surface quality that required time can guarantee workpiece again.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is front views of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Shown in attached Fig. 1 and 2, a kind of pneumatic boost pressure bench vice, it comprises bench vice assembly 1, wherein, on the described bench vice assembly 1 pneumatic cylinder assembly 2 is installed.
Described bench vice assembly 1 comprises chassis 1a, rotating disk 1b is housed on the 1a of chassis, jaw mount pad 1c is contained on the rotating disk 1b, regular jaw 1d is contained on the jaw mount pad 1c, jaw mount pad 1c inner chamber has guide runner 1e, guide rail 1f is housed in the guide runner 1e, and moving jaw 1g is installed on the guide rail 1f, and moving jaw 1g can slide along guide runner 1e with guide rail 1f;
Described pneumatic cylinder assembly 2 comprises pneumatic cylinder 2a, and the screw rod 2b of pneumatic cylinder 2a is connected with guide rail 1f, and pneumatic cylinder 2a is contained on the fixed head 2c, and fixed head 2c is fixedly mounted on the rotating disk 1b.
Described jaw mount pad 1c is installed on the rotating disk by screw 3 and pin 4.
Have pin hole 1h on the described chassis 1a.
Described guide rail 1f stretches out guide runner 1e one end baffle plate 5 is housed.
During use, open pneumatic cylinder 2a switching gas and enter pneumatic cylinder 2a generation normal pressure, promote moving jaw 1g, make the closed clamping of moving jaw 1g and regular jaw 1d, thus workpiece pressing.Closed pneumatic cylinder 2a switch, pressure reduces to form negative pressure, and workpiece is unclamped in moving jaw 1g travelling backwards, realizes stepping up and unclamping of bench vice.
The utility model can provide the clamping force clamping work pieces by pneumatic shuttle, discarded and adopted traditional hand screw rotating clamp clamping of workpieces, as long as the staff opens valve, bench vice just can clamp automatically, and the power that pneumatic means provides can be not excessive yet, can avoid bad workpiece clamp.The utility model both can alleviate workman labour, shortened workpiece and clamped the surface quality that required time can guarantee workpiece again.
