Description

Double force vise structure improvement

The invention relates to a "double-type vise structure improvement", in particular to a double-force vise invention which can effectively save the space occupied by the double force unit and increase the size of the vise opening.

According to the development of the Bühler Vise, which has been in existence for more than 10 years, the conventional bulletin No. M344940, a double force improvement device of the Becker vise, is mainly provided with a fixed cymbal at one end of the vise body and a fixed raft at the other end. a positioning portion, a lead screw is disposed between the fixed cymbal and the positioning portion for providing a movable cymbal; the lead screw receives a push rod, and uses an urging device and pushes the ejector through the push rod to actuate The component stretches the two-knuckle structure and generates a strong clamping force to force the work object, wherein the pushing device comprises a pushing block and a top holding block, the pushing block and the top block correspond to the two toggle sections The structure is provided with two card slots for assisting positioning, and a positioning structure is detachably disposed between the pushing block and the top block, and the positioning structure is coupled to the pushing block and the top block.

Although these structures can achieve the intended effect of the use of the double force vise, however, since the push block needs to process the relevant holes and the accommodating space, it is easy to cause the thickness of the push block to be thin, causing stress concentration, so generally Thickening the thickness of the pushing block to avoid the stress concentration and breaking, so that the volume of the pushing device is too large, so that the installation of the entire pushing device needs to occupy the inner space of the fixed jaw, so that only The structure can be made into a fixed structure of the fixed jaw and the body, so that the position of the anti-chip board on the top surface of the conventional vise body can not be simply and quickly milled by the processing machine, and it needs to be installed more complicated. Anti-flap board, not only The processing is troublesome and the structure is not easy to install.

The top holding block 43 has one end of each of the toggle members 42 abutting against each of the locking grooves 431, and the actuating member 44 is disposed through the through hole 412 of the pushing block 41, so that one end of the actuating member 44 can be The cover 45 is locked to the side edge of the body 10, and the guide post 451 of the cover 45 is sleeved by the compression spring 46, and the guide post of the cover 45 is The 451 is provided with the elastic member 47 and the abutting member 48 respectively, so that the end portion of the abutting member 48 is abutted against the end surface of the actuating member 44; and it is noted that the capacity of the pushing block 41 is Set the groove 411 top and bottom A concave arc 414 is formed, so that the inner corner surface of the accommodating groove 411 has a thickness 415 formed inwardly, and the inner edge surface of the accommodating groove 411 of the ejector block 41 extends inwardly from a convex step. 416.

An accommodating space 101 is disposed at a position below the fixed cymbal 13 , and the accommodating space 101 is provided for the utilizing unit 4 .

It may further include a bearing 49 that is sleeved at one end of the ejector block 41.

Among them, the bearing 49 is a needle bearing.

The elastic member 47 is a spring.

Wherein, the topping block 41 is provided with a first edge 417 adjacent to the position of the external thread portion 413 to increase the overall strength.

The toggle member 42 is composed of two links 421 and three round bars 422. The two rods 421 are respectively disposed on the opposite sides of the two rods 422, and the two links 421 are worn at the joints. The round bar 422 is pivoted such that the round bars 422 on both sides of the two links 421 are respectively abutted against the push block 41 and the top block 43.

Wherein, the two toggle members 42 are in a V-shaped relative arrangement.

With the above combination, please refer to the first to eighth figures. When the user wants to use the present invention to perform the workpiece clamping operation, it is only necessary to separately place the workpiece (not shown). Between the fixed jaw 13 and the movable jaw 14, the lead screw 31 is rotated to perform the workpiece holding operation.

When the user rotates the lead screw 31, it can drive the angular seat 12 away from the driving unit 2, and the movable movable jaw 14 is displaced toward the fixed jaw 13 to ensure the workpiece is Smooth and firm clamping, and help the subsequent processing of the workpiece, the overall operation is simple and convenient, and practical.

It should be noted that the lead screw 31 of the present invention is connected with a double force unit at one end. 4. The force unit 4 is located just below the fixed jaw 13, and when the user has clamped the workpiece on the vise of the present invention, when the user continues to operate the drive unit 2, the push of the lead screw 31 can be pushed. The rod 32 is displaced, and the end of the push rod 33 can be pushed against the front end of the actuating member 44. The inclined surface 441 of the end of the actuating member 44 can push the round rod 422 of the V-shaped toggle member 42 and make the elbow The connecting rod 421 of the joint member 42 pivots and pushes the pushing block 41, and the pushing block 41 can be displaced in the direction of the fixed jaw 13 by the driving lead screw 31, so that the workpiece can be surely clamped, so that it can be doubled. The clamping effect of the supercharged pressure not only has less overall components, but is convenient for the user to assemble and repair, and the clamping force is strong, which is very suitable for industrial processing and use, and is practical.

When the workpiece is to be removed, the lead screw 31 only needs to be rotated in the opposite direction to make it interlocked. The corner seat 12 drives the movable jaw 14 to be displaced away from the fixed jaw 13 , and the toggle member 42 returns to the V shape, so that the workpiece can be removed, and the overall operation mode is simple and convenient, and has practical utility.

It is worth noting that the receiving slot 411 of the push block 41 of the present invention is The top surface and the bottom surface respectively have a concave arc 414 (as shown in FIG. 6 ), such that the inner corner surface of the receiving groove 411 forms a thickness 415 inwardly (as shown in FIG. 5 ), and the pushing The inner edge surface of the accommodating groove 411 of the block 41 extends inwardly from a convex step portion 416 (as shown in FIG. 6), so that the volume of the ejector block 41 is small, but it is effective because the meat thickness is increased. Increasing the strength of the push block 41 as a whole can avoid stress concentration and cause the problem of cracking of the push block 41. Thus, the volume of the force unit 4 becomes smaller, and the installation of the force unit 4 does not need to be The internal space of the fixed crucible 13 is used, so that the fixed crucible 13 and the main body 10 can be designed in a separate structural state, so that the processor can perform simple and rapid milling directly on the top surface of the main body 10 by using a processing machine. Moreover, the chip board (not shown) can be directly mounted on the top surface of the body 10, which is not only easy to process, but also easy to assemble the chip board.

Furthermore, since the force unit 4 is directly housed inside the body 10, it is not required The internal space of the fixed crucible 13 is made such that the volume of the fixed crucible 13 can be relatively small, so that the opening of the movable crucible 14 and the fixed crucible 13 is increased, and the size of the workpiece that can be clamped is increased. To make it more applicable.

In summary, the double-forced vise structure of the present invention effectively improves the conventional structure. There are various shortcomings, and the main technical means of the present invention are not found in any related publications. It is in line with the application requirements of the invention patents, and the application is filed according to law, and the application for patent rights of the invention is requested.
