Description

Woodworking fixture

This creation is related to fixtures, especially for a fixture for woodworking.

According to the general decorator or the industrial processing of the wood material, in order to match the convenience of the material processing, the hand-operated woodworking fixture is used for the clamping work. The conventional woodworking fixture is made of one piece. The utility model is composed of a body and a chuck, and the clamping action can be performed by linearly reciprocating the chuck and the rod fixed at one end of the rod to the body. This is the case with the woodworking fixtures disclosed in TWM350433.

However, the clamping parts of the chuck and the body of the conventional woodworking fixture are respectively a flat shape, so it is only suitable for clamping the opposite parallel sides of the block body, for example, to clamp the two diagonals of the block body. When processing, it is easy to prevent the two diagonals of the plate body from being firmly clamped by the chuck, and the plate body is slipped or even dropped. This will result in a significant reduction in processing efficiency and even damage to the plate body, which is in need of improvement. No disadvantages.

Therefore, it is necessary to provide a novel and progressive woodworking fixture to solve the above problems.

The main purpose of this creation is to provide a woodworking fixture that can be used not only for clamping plates. The body is opposite to the two parallel sides, and can also be used to clamp the two diagonals of the block body, so the utility model is widely used and simple to operate.

In order to achieve the above object, the present invention provides a woodworking fixture comprising a body, a rod, a second chuck and two clamping portions. The body includes a first collet and an adjustment mechanism. The rod is movably disposed through the body, and the rod is adjustably displaced by the adjustment mechanism. The second chuck is disposed on the rod. The two clamping portions are respectively detachably disposed on the first clamping head and the second clamping head, and the two clamping portions respectively comprise a clamping surface facing each other, and the clamping surfaces are concavely arranged At least one longitudinal groove and at least one lateral groove.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 6 , a preferred embodiment of the present invention is shown. The woodworking fixture 1 of the present invention comprises a body 2 , a rod 3 , a second chuck 4 and two clamping portions 5 .

The body 2 includes a first collet 21 and an adjustment mechanism 22.

The rod member 3 is movably disposed through the body 2, and the rod member 3 is adjustably displaced by the adjusting mechanism 22 to perform a clamping operation by controlling the adjusting mechanism 22.

The second chuck 4 is disposed on the rod 3. In the embodiment, the second chuck 4 is detachably disposed on the rod. Preferably, the two ends of the rod member 3 can be further provided with a convex portion 31, and each of the convex portions 31 can be engaged with the second collet 4 to limit the second collet 4 to the rod member 3. in.

The two clamping portions 5 are respectively detachably disposed on the first clamping head 21 and the second clamping head 4, and the two clamping portions 5 respectively include a facing clamping surface 51, and each clamping surface 51 The recesses are provided with at least one longitudinal groove 52 and at least one lateral groove 53. In this embodiment, the longitudinal groove 52 and the lateral groove 53 are formed. In other embodiments, the lateral groove is formed. The longitudinal grooves 52 and the longitudinal grooves 52 can also be other numbers.

Preferably, each of the longitudinal groove 52 and the lateral groove 53 has a V-shaped cross section, and the groove depth of each of the longitudinal groove 52 and the lateral groove 53 is greater than 1/3 of the thickness of the clamping portion 5 to For each of the longitudinal grooves 52 and the lateral grooves 53 of the two clamping portions 5, the two opposite corners of a plate body 6 can be firmly held (as shown in FIG. 4), and in the embodiment, the longitudinal grooves are respectively The groove depth of the groove 52 and the lateral groove 53 is about 1/2 of the thickness of the intervening portion 5 to more firmly hold the two opposite corners of the plate body 6.

In addition, the longitudinal groove 52 and the two lateral grooves 53 distinguish the clamping surface 51 from the plurality of protrusions 54. In the embodiment, the protrusions 54 are substantially tapered. Preferably, each of the bumps 54 is provided with a non-slip concave-convex structure 55. In the embodiment, each of the anti-slip concave-convex structures 55 includes a plurality of triangular recesses 551, and any one of the triangular recesses 551 is parallel and adjacent to each other. The concave-convex structure 55 can prevent the bumps 54 from slipping when the opposite parallel sides of the plate body 6A are clamped (as shown in FIG. 5 and FIG. 6 ). In other embodiments, each of the concave and convex structures can also be a plurality of bumps. In the same way, the anti-slip function can be achieved.

Further, each of the clamping portions 5 is provided with a pair of connecting portions 56 on one side of the clamping surface 51, and the two socket portions 56 are respectively sleeved on the first clamping head 21 and the second clamping head. 4, each of the sleeve portions 56 defines a ring wall 57. The inner wall of at least one side of the ring wall 57 is provided with a rib 572. In the embodiment, the inner wall of the three sides of the ring wall 57 is respectively provided with the rib 572. When the ring wall 57 is sleeved on the first chuck 21 or the second chuck 4, each of the ribs 572 is fastened to the first chuck 21 or the plate portion 61 of the second chuck 4. In order to prevent each of the socket portions 56 from falling off the plate portion 61. In addition, the inner wall of each of the ring walls 57, which is not provided with one side of the ribs, is provided with a slit 573, which can make the sleeve portion 56 have a slight deformation during disassembly and assembly for convenient disassembly and assembly.

In the embodiment, each of the clamping portions 5 can be further disposed with an abutting portion 58 below the sleeve portion 56. The first clamping head 21 and the second clamping head 4 are oppositely disposed with a concave arc segment 62. The shape of the second abutting portion 58 corresponds to and is respectively abutted against the concave arc segments 62 of the first collet 21 and the second collet 4 to prevent each of the intervening portions 5 from corresponding to a portion of the concave arc segment 62. When the object is held, the object is bent and deformed in the direction of the concave arc segment 62, so that the plate body 6A cannot be firmly clamped. In the embodiment, the abutting top portion 58 can be further provided with a plurality of grooves 581 arranged at intervals. Save each of the top 58 Material cost and weight reduction.

It is worth mentioning that, as shown in FIG. 7 , when the woodworking fixture 1 is to fix an object 7 in an external manner, the second chuck 4 and the first chuck 21 may be first installed in the opposite direction. One end of the rod 3 causes the two clamping faces 51 to face in opposite directions, so that the object 7 can be externally fixed.

In summary, each of the longitudinal grooves and the lateral grooves of the carpentry fixture can firmly hold the two opposite corners of the slab body, and can also firmly hold the opposite parallel sides of the slab body.

In summary, the overall structural design, practicality and efficiency of this creation are indeed in full compliance with the needs of industrial development, and the disclosed structural creation is also an unprecedented innovative structure, so it has a "novelty" should Undoubtedly, this creation can be more effective than the conventional structure. Therefore, it is also "progressive". It fully complies with the requirements of the application requirements for new patents in the Chinese Patent Law. It is a patent application in accordance with the law, and please The bureau will review it early and give it affirmation.
