[0001] The utility model relates to the field of machining, in particular to a parallel vice capable of being quickly adjusted and fixed. Background Art

[0002] As a general fixture in the machining industry, the parallel vice is widely used in various machine tools, especially the milling machine and the drilling machine with the highest frequency. During the machining process, the parallel vice can adopt different clamping methods according to the parts for various machining operations. Due to the simple structure, rapid clamping, time-saving and labor-saving during machining, the parallel vice has universality and convenience, making it an indispensable important tool in the machining field.

[0003] Although the existing parallel vice can realize the functions of quickly adjusting and clamping the fixture, after the position adjustment is completed, it is necessary to manually operate to tighten the bolts or screws to achieve stable fixation. In the case of long-term repeated operations or large cutting depths, etc., the bolts or screws are likely to become loose due to insufficient tightening force or cutting vibration, resulting in the loosening or displacement of the movable jaw body, causing the workpiece to shift or fall off, affecting the machining accuracy and even causing safety accidents. Therefore, the utility model proposes a parallel vice adopting a hydraulic or pneumatic system and capable of being quickly adjusted and fixed. Summary of the Invention

Detailed implementation mode

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0025] In this embodiment, referring to Figures 1-6 , a quick-adjustable and fixed flat-jaw vice specifically implemented includes a base 1, a fixed jaw body 2 and a movable jaw body 3 mounted on the base 1. The fixed jaw body 2 is detachably fixed to one end of the base 1 by bolts, and the movable jaw body 3 is slidably mounted on the base 1. A fixing assembly, a clamping assembly and a quick-insert plug 4 are provided on the movable jaw body 3.

[0026] The fixing assembly includes a fixing block 5 that cooperates with the base 1 and a slidable fixing piston rod 6. One end of the fixing piston rod 6 is connected and cooperated with the fixing block 5.

[0027] The clamping assembly includes a slidable clamping piston rod 7 and a clamping block 8 mounted at one end of the clamping piston rod 7.

[0028] The quick-insert plug 4 cooperates with the fixing piston rod 6 and the clamping piston rod 7 respectively. One end of the quick-insert plug 4 is connected to an external liquid source or an external gas source.

[0029] The movable jaw body 3 is respectively provided with receiving grooves for receiving the fixing piston rod 6 and the clamping piston rod 7.

[0030] After the position adjustment of the movable jaw body 3 is completed, by controlling the external liquid source or external gas source connected to the quick-insert plug 4, the fixing piston rod 6 is pushed to make the fixing block 5 contact the base 1, and the movable jaw body 3 is firmly fixed on the base 1. Then, by pushing the clamping piston rod 7, the clamping block 8 is made to cooperate with the fixed jaw body 2 to firmly clamp the workpiece. Thus, the effect of quick adjustment and fixation is achieved. After the processing is completed, by controlling the connection of the external liquid source or external gas source, the fixing piston rod 6 and the clamping piston rod 7 lose pressure, so as to achieve the effect of loosening the part and being adjustable. The pressure can also be controlled to suit different workpieces, avoiding scratching the surface of the workpiece due to excessive clamping force and affecting the processing quality.

[0031] Furthermore, the clamping block 8 is slidably engaged with the movable jaw body 3 through a guide post 9, and the movable jaw body 3 is provided with a return spring 10 that cooperates with the guide post 9. The guide post 9 is fixed to the clamping block 8 by threaded connection. A nut is provided at one end of the guide post 9, and the return spring 10 is installed between the movable jaw body 3 and the nut. The guide post 9 enables the clamping block 8 to be smoothly pushed forward when the clamping piston rod 7 is pushed. When the driving force of the clamping piston rod 7 is lost, the return spring 10 enables the clamping block 8 to quickly approach the movable jaw body 3, thereby loosening the part.

[0032] Furthermore, limiting grooves 11 are provided on both sides of the base 1, and the movable jaw body 3 is provided with limiting blocks 12 that cooperate with the limiting grooves 11. Through the cooperation of the limiting grooves 11 and the limiting blocks 12, the sliding of the movable jaw body 3 on the base 1 becomes more stable, avoiding possible left-right shaking or deviation during the adjustment process, and further improving the clamping accuracy and stability. A gap is left between the limiting grooves 11 and the limiting blocks 12, enabling the movable jaw body 3 to be easily pushed during adjustment. When fixation is required, the fixing block 5 pushes the movable jaw body 3 upward to make the limiting block 12 closely adhere to the limiting groove 11.

[0033] Furthermore, the limiting groove 11 is provided with an upwardly inclined guiding structure 13. When the fixing block 5 cooperates with the base 1, the design of the guiding structure 13 effectively reduces the impact when the limiting block 12 cooperates with the limiting groove 11, enabling the limiting block 12 to move upward smoothly. It avoids the rapid fitting of the limiting block 12 and the limiting groove 11, which may cause the sudden stop or impact of the movable jaw body 3, resulting in damage to the movable jaw body 3 or the base 1. It prolongs the service life of the bench vice.

[0034] Furthermore, a rotatable positioning plate 14 is installed on one side of the fixed jaw body 2, and a slidable positioning pin 15 is provided on the positioning plate 14. The positioning plate 14 is provided with a U-shaped groove. This enables the position of the positioning pin 15 to be adjusted according to the needs of the part to meet the positioning requirements of different parts.

[0035] Furthermore, a limiting baffle 16 is provided at one end of the base 1. The limiting baffle 16 provides a certain stroke limit for the movable jaw body 3, avoiding the dropping and bumping of the movable jaw body 3 caused by improper operation, which may affect the accuracy and stability of the movable jaw body 3.

[0036] Furthermore, the base 1 is provided with an outwardly extending mounting plate 17, and the mounting plate 17 is provided with a kidney-shaped groove 18. Through the kidney-shaped groove 18 on the mounting plate 17, the bench vice can be conveniently installed on various workbenches, such as machine tools, milling machines, drilling machines, etc. The design of the kidney-shaped groove 18 enables the mounting plate 17 to have a certain adjustment range, and the position of the bench vice can be adjusted according to actual needs to adapt to different working environments and processing requirements.

[0037] The beneficial effects of the present utility model: Through the cooperation of the fixing block 5 that cooperates with the base 1, the slidable fixed piston rod 6, and the quick-insert plug 4, after the position adjustment is completed, the movable jaw body 3 can be quickly fixed by controlling the oil pressure or air pressure switch, and the workpiece can be quickly clamped through the cooperation of the clamping piston rod 7 and the clamping block 8 with the fixed jaw body 2. This makes the bench vice more convenient and fast during the adjustment process, ensuring the machining accuracy and safety. Thus, the practicality and convenience of the bench vice are improved.

[0038] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed above in the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the technical solution scope of the present utility model, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, but as long as it does not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present utility model all fall within the scope of the technical solution of the present utility model.
