The jig 100 provided in the embodiment of the present application is applied to clamping a workpiece. The workpiece may be a drill or the like, and is not particularly limited.

Referring to fig. 1 and fig. 3, an embodiment of the present application provides a jig 100, which includes a body 110, an adjusting member 120, and a rubber sleeve 130. The body 110 includes a sleeve portion 111 and a plurality of extension bars 112 extending along the axial direction of the sleeve portion 111, the plurality of extension bars 112 are connected to the sleeve portion 111 around the axial interval of the sleeve portion 111, and the plurality of extension bars 112 surround and are formed with mounting holes for workpieces to penetrate. An adjustment member 120 is coupled to each extension bar 112 and is configured to apply an adjustable clamping force to the plurality of extension bars 112 to cause the body 110 to loosen or clamp a workpiece positioned within the mounting aperture. The rubber sleeve 130 is sleeved on the sleeving part 111 for hand holding.

In the above-mentioned jig 100, during actual operation, the workpiece is inserted into the mounting hole, and a large tightening force is applied to the plurality of extension bars 112 through the adjusting member 120, and under the tightening force, the plurality of extension bars 112 have a tendency of approaching each other, and at this time, the plurality of extension bars 112 jointly act on a clamping force of the workpiece, thereby realizing clamping of the workpiece. The worker holds the rubber sleeve 130 to apply force to the body 110, and the body 110 drives the workpiece to move. When the tightening force applied by the adjustment member 120 becomes small, each extension bar 112 returns to the free state, and the clamping force applied to the workpiece is released to release the workpiece.

Compared with the prior art, when the workpiece is driven to move, a worker does not need to directly hold the workpiece but hold the workpiece on the rubber sleeve 130, so that the friction force borne by the hand of the worker is reduced, the hand comfort of the worker is increased, and the production enthusiasm of the worker is improved. Meanwhile, the extension bars 112 are cantilever-shaped, and the mounting holes formed by enclosing the plurality of extension bars 112 can be adapted to a workpiece having an outer diameter slightly larger than the mounting holes or having an outer diameter slightly smaller than the mounting holes, so that the jig 100 has a wider application range.

The rubber sleeve 130 may be a silica gel sleeve, a rubber sleeve, or the like.

Wherein, each extension bar 112 is arranged on the socket part 111 around the axial interval of the socket part 111, so that each extension bar 112 is in a cantilever shape, and has a tendency that each extension bar 112 approaches each other under the clamping force, thereby generating the clamping force for clamping the workpiece.

Optionally, the number of the extension bars 112 is four, and the cross sections of the four extension bars 112 are circular arc-shaped.

Preferably, the socket 111 is integrally formed with the plurality of extension bars 112. Thus, the strength of the body 110 is improved, and the clamping reliability is improved.

In some embodiments, the adjustment member 120 may be a clamp that simultaneously engages each of the extension strips 112 and is capable of applying a tightening force such that each of the extension strips 112 have a tendency to move toward each other. Wherein the clamping force applied to the extension bar 112 can be adjusted by adjusting the size of the bayonet of the clamp. Of course, the following embodiments may be adopted.

In some embodiments, the adjuster 120 is configured to adjust the tightening force applied to the plurality of extension bars 112 by changing the length of the connection with the plurality of extension bars 112. When the connecting length of the adjusting member 120 and each extension bar 112 is longer, the clamping force applied by the adjusting member is larger, so that the clamping force applied to the workpiece by all the extension bars 112 is larger; as the connecting length of the adjusting member 120 to each extension bar 112 is shorter, the tightening force applied thereto is smaller, so that the clamping force applied to the workpiece by all the extension bars 112 becomes smaller.

In an embodiment, referring to fig. 2 and 4, the body 110 has a first internal thread section extending along an axial direction of the sleeve portion 111, the first internal thread section is disposed on an inner wall of the plurality of extending strips 112, the adjusting member 120 has an external thread section, the sleeve portion 111 has a through hole communicating with the mounting hole, one end of the adjusting member 120 penetrates through the through hole along the axial direction of the sleeve portion 111 and extends into the mounting hole, and the external thread section of the adjusting member 120 is engaged with the first internal thread section.

The first internal thread section is disposed on the inner wall of the extension bars 112, which means a first internal thread section defined by the internal threads on the inner wall of the extension bars 112.

In actual operation, the adjusting member 120 goes deep into the mounting hole through the through hole of the sleeve 111 and is simultaneously screwed with the internal threads on the inner walls of the plurality of extension bars 112, thereby applying a tightening force to all the extension bars 112. With the continuous screwing of the adjusting member 120, the engaging length of the external thread section of the adjusting member 120 and the first internal thread section becomes larger, so that the tightening force exerted by the adjusting member 120 becomes larger and larger, and further the clamping force exerted by all the extension bars 112 on the workpiece becomes larger and larger, thereby clamping the workpiece. When the adjusting member 120 is rotated reversely, the engagement length of the external thread section of the adjusting member 120 and the first internal thread end becomes smaller, the tightening force applied by the adjusting member 120 to the extension bars 112 becomes smaller, and the clamping force applied by all the extension bars 112 to the workpiece becomes smaller, so that the body 110 can loosen the workpiece.

Wherein, the adjusting member 120 may be a screw, a bolt, etc. The profile of the externally threaded section of the adjustment member 120 may be trapezoidal, which provides a greater radial force so that the individual extension bars have a tendency to close together in a radial direction to clamp the workpiece.

Further, the adjusting member 120 has a large diameter end and a small diameter end, the radial dimension of the large diameter end of the adjusting member 120 gradually decreases toward the small diameter end, and the small diameter end is disposed near an end of the extension bar 112 departing from the sleeve portion 111 compared to the large diameter end. At this time, the adjusting member 120 has a certain taper, and when the adjusting member 120 has a certain taper, the first internal thread section is also an internal thread section having a certain taper.

In practical applications, when the adjusting member 120 has a certain taper, the relative distance between the extending strips 112 becomes smaller and smaller as the adjusting member 120 is screwed in, so that the clamping force of the extending strips 112 on the workpiece becomes larger and larger, which helps to achieve more reliable clamping of the workpiece.

Wherein, the adjusting member 120 may be a taper screw or a taper bolt.

Further, referring to fig. 2 and 4, a limiting portion 113 is convexly disposed on an inner wall of the at least one extending bar 112, and the first internal thread section is disposed between the limiting portion 113 and the socket portion 111. At this time, the maximum screwing length of the adjusting screw is limited by the limiting part 113, a certain clamping space is reserved for the workpiece, and the clamping reliability of the workpiece is ensured.

The limiting portion 113 may be a limiting block or a limiting strip, and the specific shape is not limited.

Furthermore, each extension bar 112 is provided with a limiting portion 113, the distance from each limiting portion 113 to one end of the extension bar 112 away from the sleeve portion 111 is equal, and a clamping portion 114 for clamping the workpiece is formed by the portions of the plurality of extension bars 112 located between the limiting portions 113 and the end of the extension bar 112 away from the sleeve portion 111.

At this time, the limiting portions 113 of the extending strips 112 are arranged at the same axial position of the sleeving portion 111, so that the limiting portions 113 can be simultaneously in limiting abutting contact with the adjusting screws, and the limiting strength is improved. Meanwhile, the clamping part 114 is used for clamping the workpiece, the clamping depth of the workpiece is also limited by the limiting part 113, and the situation that the workpiece cannot be clamped due to the fact that the workpiece is inserted too deeply to influence the screwing length of the adjusting screw can be avoided.

Preferably, the inner wall of the clamping portion 114 is provided with a rough layer. Therefore, the workpiece is in contact with the rough layer, which is beneficial to improving the friction force between the workpiece and the body 110, thereby improving the stability of the body 110 for clamping the workpiece.

Wherein the rough layer may be made of a friction-resistant material, such as a carbon fiber friction material layer. Alternatively, the rough layer is machined into the textured layer on the extension strips 112.

Additionally, in some embodiments, the inner wall of the socket 111 is provided with a second internal thread section capable of engaging with the external thread section. At this time, when the adjusting screw is withdrawn to the state that the external thread section is not completely meshed with the first internal thread section, the adjusting screw can be meshed with the second internal thread section of the sleeving part 111, so that the adjusting screw is prevented from sliding out of the body 110, and the operation difficulty is increased.

In other embodiments, an external thread section may be disposed on the outer wall of the extension bar 112, the adjusting member 120 is an adjusting sleeve, an internal thread section is disposed in the adjusting sleeve, and the adjusting member 120 and the plurality of extension bars 112 are connected together by using the internal thread section of the adjusting sleeve and the external thread section on the outer wall of the extension bar 112.

In some embodiments, the rubber sleeve 130 is detachably sleeved on the sleeve portion 111. So, when the wear-resisting effect of gum cover 130 is not good, be convenient for change gum cover 130, improve workman's travelling comfort. When the screwing length of the adjusting screw needs to be adjusted, the lower rubber sleeve 130 is detached, and adjustment is facilitated.

Of course, the rubber sleeve 130 may be fixedly fitted on the fitting portion 111. At this time, the rubber sleeve 130 is provided with an opening for the adjustment screw to pass through. When the adjusting screw needs to be adjusted, the screwing length of the adjusting screw is adjusted through the opening.

In some embodiments, the rubber sleeve 130 is provided with an anti-slip groove. Thus, the friction force between the worker and the rubber sleeve 130 is increased through the anti-slip groove, and the operability is improved.

Wherein, the quantity of antiskid groove is a plurality of, and a plurality of antiskid grooves are around the axial interval arrangement of cup jointing portion 111, and each antiskid groove all follows the axial extension of cup jointing portion 111.

The jig 100 provided in the embodiment of the present application has at least the following beneficial effects:

1, during actual operation, a workpiece is inserted into the mounting hole, a large tightening force is applied to the plurality of extension bars 112 through the adjusting piece 120, the plurality of extension bars 112 have a tendency of approaching each other under the tightening force, and at the moment, the plurality of extension bars 112 jointly act on the workpiece with a clamping force, so that the workpiece is clamped. The worker holds the rubber sleeve 130 to apply force to the body 110, and the body 110 drives the workpiece to move. When the tightening force applied by the adjustment member 120 becomes small, each extension bar 112 returns to the free state, and the clamping force applied to the workpiece is released to release the workpiece. Compared with the prior art, when the workpiece is driven to move, a worker does not need to directly hold the workpiece but hold the workpiece on the rubber sleeve 130, so that the friction force borne by the hand of the worker is reduced, the hand comfort of the worker is increased, and the production enthusiasm of the worker is improved. Meanwhile, the extension bars 112 are cantilever-shaped, and the mounting holes formed by enclosing the plurality of extension bars 112 can be adapted to a workpiece having an outer diameter slightly larger than the mounting holes or having an outer diameter slightly smaller than the mounting holes, so that the jig 100 has a wider application range.

2) The adjuster 120 is configured to adjust the tightening force applied to the plurality of the extension bars 112 by changing the connection length with the plurality of the extension bars 112. When the connecting length of the adjusting member 120 and each extension bar 112 is longer, the clamping force applied by the adjusting member is larger, so that the clamping force applied to the workpiece by all the extension bars 112 is larger; as the connecting length of the adjusting member 120 to each extension bar 112 is shorter, the tightening force applied thereto is smaller, so that the clamping force applied to the workpiece by all the extension bars 112 becomes smaller. So, conveniently adjust the clamp force that changes the body.

3) The adjusting member 120 has a taper, and as the adjusting member 120 is screwed in, the relative distance between the extension bars 112 becomes smaller and smaller, so that the clamping force of the extension bars 112 on the workpiece becomes larger and larger, which helps to achieve more reliable clamping of the workpiece.
