Abstract

The utility model provides a quick advance and retreat clamping vice, comprising a base, a fixing vice base and a movable vice block. The utility model is characterized in that the inner cavities of the base and the fixing vice base are provided with a rack bar, and the inner end of a screw rod is provided with a sliding block and a control plate. The sliding block is provided with screw thread which is matched with the screw rod, making the sliding block move in the parallel direction along the screw rod. The sliding block is provided with a wheel gear and an engaged claw, and the wheel gear is engaged with the rack bar of the inner cavity of the fixing vice base. The engaged claw can generate the clutch action to the wheel gear, and the action of the engaged claw (15) is controlled by the screw rod (12) driving the sliding block (6) to adjust the distance of the sliding block (6) and the control plate (8). Compared with the existing bench vice, the utility model is simple in structure, and the appearance of the utility model is similar to the existing bench vice. When the quick advance and retreat clamping vice is used, the effect of quickly advancing and retreating the movable vice blocks to clamp or loose the work pieces can be achieved through the combination of shaking a handle, pushing and pulling the movable vice blocks. The utility model can greatly quicken operation speed and improve work efficiency. The operation mode of the utility model is similar to the old type bench vice, and the utility model is very convenient.

Description

The fast advance and retreat clamping bench clamp

Technical field

The utility model relates to a kind of hardware ﹠ tools, particularly a kind of bench vice.

Background technology

Old-fashioned bench vice originally is made of base, fixing pincers seat and active clamp block, fixing pincers seat is fixedly connected on the base, active clamp block is located at the inner chamber of fixing pincers seat and can be moved as run-in index, active clamp block is the structure of 7 fonts, it can form a jaw that is used for clamping work pieces with fixing pincers seat, active clamp block drives by screw mandrel and the Si Ya that is arranged in fixing pincers seat and the active clamp block, and an end of screw mandrel stretches out fixing pincers seat outside and one handle is installed.Screw mandrel is rotated drive the silk tooth that is fixed on the active clamp block by shaking handle, thereby drive active clamp block, a jaw of forming with fixing pincers seat is dwindled or enlarges, with the workpiece clamping or unclamp.This bench vice has advantages such as easy manufacturing simple in structure, is widely used, and its weak point is in the time workpiece will being clamped or unclamp, and need shake the handle multi-turn, particularly to the workpiece of big part, wastes time and energy more, influences operating efficiency.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective of existing old-fashioned bench vice, designs a kind of bench vice that can clamp fast or unclamp.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of fast advance and retreat clamping bench clamp that the utility model provides, constitute by base, fixing pincers seat and active clamp block, fixing pincers seat is fixedly connected on the base, active clamp block is located at the inner chamber of fixing pincers seat and can be moved as run-in index, active clamp block is the structure of 7 fonts, it can form a jaw that is used for clamping work pieces with fixing pincers seat, and a screw mandrel that is installed in the active clamp block inner chamber, an end of screw mandrel stretch out active clamp block outside (being the outer end) and handle is installed.It is characterized in that:

Inner chamber at base and fixing pincers seat is provided with a tooth bar, is provided with a slide block and a control panel in the inner of screw mandrel, and this slide block is provided with the screw thread that cooperates with screw mandrel makes this slide block to do parallel moving along screw mandrel; This slide block is provided with a gear and and nibbles pawl, gear meshes with the tooth bar of fixing pincers seat inner chamber, nibble pawl and can produce clutch action gear, when nibbling pawl and enter the between cog of gear, lock gear can not be rotated, when nibbling pawl and leave the between cog of gear, gear can freely rotate, and the action of nibbling pawl promotes slide block by screw mandrel and controls.

Example with accompanying drawing is that the utility model is further described below.

The drawing explanation

Fig. 1 is structure chart of the present utility model (a non-locking state);

Fig. 2 is structure chart of the present utility model (locking state).

The specific embodiment

As depicted in figs. 1 and 2,

A kind of fast advance and retreat clamping bench clamp that the utility model provides, constitute by base 1, fixing pincers seat 9 and active clamp block 11, fixing pincers seat 9 is fixedly connected on the base 1, active clamp block 11 is located at the inner chamber of fixing pincers seat 9 and can be moved as run-in index, active clamp block 11 is 7 font structures, it can form a jaw 10 that is used for clamping work pieces with fixing pincers seat 9, article one, screw mandrel 12 is installed in the inner chamber of active clamp block 11, one end of screw mandrel 12 stretches out active clamp block 11 outsides (being the outer end) and handle 13 is installed, and it is characterized in that:

Inner chamber at base 1 and fixing pincers seat 9 is provided with a tooth bar 2,

Be provided with a slide block 6 and a control panel 8 in the inner of screw mandrel 12, this slide block 6 is provided with the threaded block 5 that cooperates with the screw 7 of screw mandrel 12, makes this slide block 6 to do parallel moving along screw mandrel 12;

Slide block 6 is provided with a gear 3 and and nibbles pawl 15, gear 3 meshes with the tooth bar 2 of fixing pincers seat 9 inner chambers, nibble pawl 15 and can produce clutch action gear 3, when the lock tooth 4 of nibbling pawl 15 enters the between cog of gear 3 (as Fig. 2), lock gear 3 can not be rotated, when the lock tooth 4 of nibbling pawl 15 leaves the between cog of gear 3 (as Fig. 1), gear 3 can freely rotate, and the action of nibbling pawl 15 promotes slide block 6 adjusting sliders 6 by screw mandrel 12 and controls with the distance of control panel 8.

Work when initial, should shake handle 13, make unlock state as shown in Figure 1, at this moment can push-and-pull active clamp block 11, make jaw 10 be fit to the size of workpiece fast and workpiece is put into jaw 10 places.

Shake handle 13 clockwise, screw mandrel 12 is rotated, the slide block 6 that is positioned at screw mandrel 12 other ends moves right, nibble also moving right of pawl 15, slide block 6 reduces with the distance of control panel 8, nibbles pawl 15 and rotates under the effect of spring 114, lock tooth 4 enters the between cog (as Fig. 2) of gear 3, at this moment gear 3 can not rotate, and slide block 6 is inactive, and active clamp block 11 is inactive.

At screw mandrel 12, slide block 6, nibble under the acting in conjunction of pawl 15, gear 3 and tooth bar 6, further enforce handle 13, active clamp block 11 is further drawn close to fixing pincers seat 9 directions, make jaw 10 clamping work pieces.

Shake handle 13 in the other direction, can make jaw 10 unclamp workpiece (process is omitted).

With the contrast of existing bench vice, the utility model is simple in structure, and profile is similar to existing bench vice, during use by shaking hand Handle and sliding active pincers piece combines, and can reach the fast advance and retreat active clamp block with Workpiece clamping or the effect of unclamping, this practicality The novel speed that can speed operations widely improves work efficiency, and mode of operation is also similar with old-fashioned bench vice, very convenient.
