Referring to fig. 1 to 6, the present embodiment provides a portable woodworking fixture, which includes a guide rod 10, a first clamping member 20, a second clamping member 30 and a driving mechanism 40, wherein the first clamping member 20 and the second clamping member 30 are both sleeved on the guide rod 10 and can freely slide along the guide rod 10. Specifically, the first clamping member 20 is provided with a first through hole 201 penetrating therethrough, the second clamping member 30 is provided with a second through hole 301 penetrating therethrough, and the guide rod 10 is sequentially inserted into the first through hole 201 and the second through hole 301, so that the first clamping member 20 and the second clamping member 30 can both freely slide along the guide rod 10. However, a limiting structure 50 is arranged between the bottom of the guide rod 10 and the bottom of the first through hole 201, the first clamping member 20 can slide freely along the guide rod 10 only when the guide rod 10 is lifted upwards relative to the first clamping member 20, when the first clamping member 20 bears the gravity of the guide rod 10, the limiting structure 50 enables the first clamping member 20 to not slide relative to the guide rod 10, and a driving mechanism 40 is connected to the second clamping member 30, the driving mechanism 40 is used for driving the second clamping member 30 to slide along the guide rod 10, and when the second clamping member 30 gradually approaches the first clamping member 20 in the sliding process, the second clamping member 30 and the first clamping member 20 are used for jointly clamping the wood 80 to be processed.
In this embodiment, the limiting structure 50 specifically includes a screw 501 and an internal thread 502 disposed on a wall of the bottom of the first through hole 201, and preferably, in this embodiment, a half nut 202 is embedded in the bottom of the first through hole 201, where the half nut 202 has the internal thread 502, and the screw 501 is fixed on the bottom of the guide rod 10, preferably, after the screw 501 is fixed on the guide rod 10, the axial direction of the screw 501 is the same as the length direction of the guide rod 10, and both the screw 501 and the guide rod 10 are inserted into the first through hole 201, and when the guide rod 10 is lifted up relative to the first clamping member 20, the screw 501 and the nut 202 do not interfere with each other, i.e., the screw 501 is not limited by the internal thread 502 of the nut 202, and at this time, the first clamping member 20 can slide freely along the guide rod 10; when the guide bar 10 is put down, the guide bar 10 will due to free gravity cause the screw 501 to be embedded downwards into the internal thread 502 of the nut 202, at which time the nut 202 cannot move relative to the screw 501 due to the restriction of the internal thread 502 of the screw 501, and thus the entire first clamping member 20 cannot slide freely relative to the guide bar 10.
It is added to the above description that the upper portion of the nut 202 is cut such that the nut 202 only retains at most half of the internal threads 502 that are upwardly open, and the external diameter of the internal threads 502 is slightly greater than or equal to the external diameter of the screw 501, such that the external threads on the exterior of the screw 501 are embedded within the internal threads 502.
It is further added that the length of the guide rod 10 is longer than the length of the screw 501, i.e. the guide rod 10 is convex with respect to the screw 501, and the portion of the guide rod 10 protruding with respect to the screw 501 is inserted into the second through hole 301 of the second clamping member 30, so that the second clamping member 30 is not limited by the screw 501 when sliding with respect to the guide rod 10, and in fact, the shape of the second through hole 301 and the shape of the guide rod 10 are adapted. In addition, the outer shape of the guide bar 10 is a polygonal structure having a non-cylindrical shape, so that the first and second clamps 20 and 30 do not have a problem of rotation when the first and second clamps 20 and 30 slide with respect to the guide bar 10, to ensure that the first and second clamps 20 and 30 maintain an inherent posture when sliding with respect to the guide bar 10.
The driving mechanism 40 specifically includes a fixing seat 401, a driving rod 402, a first nut 403, a second nut 404, and a sealing piece 405, where the fixing seat 401 is provided with a through third through hole 4011, the shape of the third through hole 4011 is also adapted to the shape of the guide rod 10, one end of the guide rod 10 beyond the screw 501 is inserted into the third through hole 4011, the fixing seat 401 and the guide rod 10 are fixedly connected, and the fixing seat 401 is located at one side of the second clamping member 30 opposite to the first clamping member 20, and during actual operation, the fixing seat 401 can be slid along the guide rod 10 according to actual conditions to adjust the position of the fixing seat 401. The second clamping member 30 is provided with a groove 302 on a surface facing the fixing seat 401, the first nut 403 is received in the groove 302, and the sealing piece 405 is used for blocking part of the groove 302 so as to prevent the first nut 403 from falling out, the driving rod 402 is connected to the fixing seat 401, the driving rod 402 is preferably a screw rod, and the driving rod 402 passes through the sealing piece 405 and is in threaded connection with the first nut 403, so that when the driving rod 402 is rotated, the second clamping member 30 can be driven to be close to or far from the first clamping member 20. And a second nut 404 is also screwed onto the driving rod 402, the second nut 404 being used to adjust the driving stroke of the driving rod 402.
The following summarizes the use of the woodworking jig of this embodiment:
Firstly, placing the wood 80 to be processed on the upper surface of the guide rod 10, positioning the wood 80 to be processed between the first clamping piece 20 and the second clamping piece 30, lifting the guide rod 10 upwards relative to the first clamping piece 20, moving the first clamping piece 20 to the adjacent position of the wood 80 to be processed along the guide rod 10, putting down the guide rod 10, embedding a screw 501 below the guide rod 10 into an internal thread 502 arranged in the first clamping piece 20, wherein the first clamping piece 20 cannot slide relative to the guide rod 10 under the action of external force, and then sliding the second clamping piece 30 along the guide rod 10 by operating the driving rod 402, so that the wood 80 to be processed can be clamped by the first clamping piece 20 and the second clamping piece 30 together, and the woodworkers can conveniently process the wood 80 on the customer site; after the processing is completed, the woodworking staff can unscrew the driving rod 402 first to separate the first clamping member 20 and the second clamping member 30 from each other for a small distance, and at this time, the woodworking staff can easily take away the processed timber 80 upwards.
It should be noted that, as shown in fig. 6, when the width of the wood 80 is large, two or more sets of woodworking jigs according to the present embodiment may be used to clamp the wood 80, so as to improve the reliability of clamping the wood 80.
To sum up, this technical scheme can be convenient for carpenter personnel to carry out processing operation to timber 80 at the customer scene, and the anchor clamps of this technical scheme have simple structure and portable's advantage to improve carpenter personnel's work efficiency by a wide margin, avoid influencing customer experience because of work efficiency is low and repeated a plurality of service of going up to the door.
The foregoing description of the preferred embodiments of the present utility model has been provided for the purpose of illustrating the general principles of the present utility model and is not to be construed as limiting the scope of the utility model in any way.
