Description

A kind of clamping fixture

Technical field:

The utility model relates to a kind of clamping fixture, relates in particular to a kind of clamping fixture that is applied on the Drilling machines bench face product be gripped rear boring, tapping.

Background technology:

At present, when needs are finished boring, tapping procedures, the way that adopts is that workpiece is fixed on the work top of drilling machine, offer at work top itself and to grip the hole, manually be fixed, this fixed clamp device is too simple, be easy to cause boring, tapping error to occur, and because clamping is unstable, when drill bit is holed to workpiece, cause easily the workpiece skew, drill bit can produce and fracture, there are certain hazards in personnel people trade union, and clamping is too loaded down with trivial details, operating efficiency is also lower.

Summary of the invention:

The technical problem that the utility model solves provides that a kind of structural design is ingenious be used to overcoming defects, and hole after fixing applicable to the different size piece-holder, the clamping fixture of tapping.

The technical scheme in the invention for solving the technical problem is: a kind of for holing on the drilling machine, the clamping fixture of tapping, this clamping fixture is arranged on the work top of drilling machine, described clamping fixture comprises fixed block and movable block, described fixed block is bolted on the work top, described fixed block is connected the first bolt and is connected the bolt connection with movable block, described the first bolt and the second bolt pass movable block, corresponding medial surface on described fixed block and movable block offers two semicircle shrinkage pools, offer respectively groove one and groove two at described fixed block and the corresponding medial surface of movable block, in groove one and groove two, be provided with spring, one end of spring withstands groove one, and the other end withstands groove two; The external part of described the first bolt connects one handle.

Further, be fixed in order to make things convenient for manually-operated, described handle forms " T " font by transverse handle and vertical handle, and the junction of transverse handle and the handle of being connected adopts the mode of welding to connect.

Further, avoid staff to produce the phenomenon of landing at the handle place, be socketed with rubber case at the head of described transverse handle and vertical handle.

Further, fastening in order to guarantee movable block and fixed block clamping, the head of described the second bolt and the junction of movable block are provided with packing ring.

The beneficial effects of the utility model are: the retaining part of this clamping device is two semicircle shrinkage pools, the end that is connected to fixed block that the second bolt is fixing with an end of movable block, regulate the first bolt by handle, realize the clamping and the action that separates of movable block and fixed block, when finishing clamping work, handle turns clockwise, and movable block is pressed on the fixed block, and two semicircle shrinkage pools grip product; Unclamp when action finishing, handle is rotated counterclockwise, and this moment, spring played a role, with the movable block bullet from fixed block; This clamping device structural design is ingenious, has improved the clamping machining accuracy, is easy to manually-operated.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the schematic diagram of the utility model in implementation.

Among the figure: 1, drilling machine 2, joystick 3, work top 31, cannelure 4, drill bit 5, boring clamping fixture 51, fixed block 52, movable fast 53, shrinkage pool 6, spring 71, the first bolt 72, the second bolt 8, packing ring 91, transverse handle 92, vertical handle 10, rubber case.

The specific embodiment:

A kind of for holing on the drilling machine as illustrated in fig. 1 and 2, the clamping fixture of tapping, this clamping fixture 5 is arranged on the work top 3 of drilling machine 1, offer cannelure 31 at described work top 3, clamping fixture 5 is to be bolted, the fixing position of bolt can be along moving in the cannelure 31, reach the purpose that movable installation position is put, described clamping fixture comprises fixed block 51 and movable block 52, described fixed block 51 is connected with movable block and is connected by the first bolt 71 and the bolt 72 of being connected, described the first bolt 71 and the second bolt 72 pass movable block 52, corresponding medial surface on described fixed block 51 and movable block 52 offers two semicircle shrinkage pools 53, these two semicircle shrinkage pools 53 form clamp area, it is drill bit 4 directly over clamp area, offer respectively groove one and groove two (not shown) at described fixed block 51 and movable block 52 corresponding medial surfaces, be provided with spring 6 in groove one and groove two, an end of spring 6 withstands groove one, and the other end of spring withstands groove two; The external part of described the first bolt 71 connects one handle.

Further, be fixed in order to make things convenient for manually-operated, described handle forms " T " font by transverse handle 91 and vertical handle 92, and the junction of transverse handle 91 and the handle of being connected 92 adopts the mode of welding to connect.

Further; avoid staff to produce the phenomenon of landing at the handle place; head at described transverse handle 91 and vertical handle 92 is socketed with rubber case 10, and the people holds rubber case 10 and prevents the phenomenon of skidding, and has also protected in a certain sense operator's personal safety.
