Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] like Figure 1-3 As shown in Embodiment 1 of this utility model, an angle-adjustable hand saw fixture includes: a base 4, a clamping seat 16 for clamping is fixed on the base 4 by bolts, a slot seat 11 is fixed on the base 4 by bolts, a first angle adjustment block 12a is movably inserted into the slot seat 11, one side of the angle adjustment block 12a is a slope (the angle of the slope is 40° or 60°, and the specific slope angle can be designed as needed), and a first magnetic ring 10a is fixedly provided on the slope, and an insert block 15 is integrally formed at the bottom of the first angle adjustment block 12a. The insert block 15 is movably inserted into the groove of the slot seat 11, and one side of the first angle adjustment block 12a is in contact with one side of the clamping seat 16. The consumable plate 9 prevents damage to the base 4 when the hand saw is cutting and is easy to replace. When the hand saw is not in use, it can be adsorbed on the first magnetic ring 10a.
[0028] A ruler base 17 is bolted to the base 4, and a ruler rod 13 is fixedly mounted on the ruler base 17. A U-shaped seat 5 is movably fitted onto the ruler rod 13. A stop block 6 is fixedly mounted on one side of the U-shaped seat 5, and a threaded rod 7 is threaded into the other side of the U-shaped seat 5. A friction disc 8 is fixedly mounted at the end of the threaded rod 7. A push rod 1 is movably inserted into a protrusion on one side of the clamping seat 16, and a chuck 2 is fixedly mounted at the end of the push rod 1. The U-shaped seat 5 can slide on the ruler rod 13 to adjust the measuring distance. The threaded rod 7, the friction disc 8, and the U-shaped seat 5 cooperate, as do the clamping seat 16, the threaded rod 14, and the push rod. The U-shaped seat 5 and the clamping seat 16 have threaded grooves, and the preload generated by applying torque can effectively prevent… The threads loosen under vibration or impact. The bolts and threaded grooves further improve vibration resistance by increasing the frictional resistance of the support surface or thread surface. The threaded connection does not require damage to the parts, is detachable, and is convenient for equipment maintenance and adjustment. The stop block 6 is used to hold the object to be measured. The object is held against one side of the clamping seat 16. The threaded rod 7 drives the friction disc 8 to rotate together and cooperates with the threaded hole on the U-shaped seat 5. The clamping seat 16 has a threaded rod 14 for fastening the push rod 1. The end of the push rod 1 is fixedly provided with a push handle 3. The top side of the base 4 is fixedly provided with a consumption plate 9 by bolts. One side of the consumption plate 9 is attached to one side of the clamping seat 16. One end of the scale rod 13 is attached to the protrusion on one side of the clamping seat 16.
[0029] Step 1: When using, move the U-shaped seat 5 to drive the stop block 6 to measure the length that needs to be cut on the object, and then tighten the threaded rod 7 to set the length that the object needs to be cut to.
[0030] Step 2: Then push the push rod 1 to drive the chuck 2 to clamp the object to be cut on the clamping seat 16, and then tighten the threaded rod 14;
[0031] Step 3: According to the cutting angle requirements, insert the first angle adjustment block 12a into the slot 11 so that the hand saw can use the force of the first angle adjustment block 12a to cut.
[0032] Clamp the ruler rod 13, push the push rod 1 on the clamping seat 16 to clamp the object to be cut, and then tighten and fix it on the clamping seat 16 with the threaded rod 14. The push handle 3 is easy to grip and easy to use. The chuck 2 slides on the clamping seat 16 to play a limiting role. The clamping is quick and convenient. The height of the first angle adjustment block 12a, the chuck 2 and the clamping seat 16 can be higher to facilitate compatibility with larger hand saws and objects to be cut, so that the first magnetic ring 10a does not affect the cutting of the hand saw. When the consumable plate 9 is worn out, the bolts on the consumable plate 9 can be unscrewed directly and a new consumable plate 9 can be replaced. The ruler seat 17 can be unscrewed from the base 4 to remove the clamping ruler rod 13. Similarly, the slot seat 11 can be removed from the base 4, or the bolts on the clamping seat 16 can be unscrewed to remove the clamping seat 16.
[0033] Tooth marks are provided between the clamping seat 16 and the chuck 2 to increase friction; a rubber pad may also be provided between the clamping seat 16 and the chuck 2 to increase friction. The tooth mark structure, through the mechanical interlocking of the concave and convex surfaces, effectively increases the friction between the clamping parts and the workpiece. The uniform distribution of the tooth marks can disperse the clamping force and avoid workpiece deformation caused by local stress concentration. The elasticity and flexibility of the rubber pad can prevent scratches or indentations on the workpiece surface during clamping, and the anti-slip properties of the rubber can effectively absorb vibration.
[0034] The height of the first angle adjustment block 12a is set higher than the object being cut, and the height of the first magnetic ring 10a is also set higher than the object being cut, so as not to hinder the hand saw from cutting the object normally.
[0035] The first angle adjustment block 12a rests against one side of the clamping seat 16, just enough to expose the object to be sawed. The handsaw leans against the side of the first angle adjustment block 12a for leverage, and can be aligned with the object to be cut from top to bottom.
[0036] Use a torque wrench to ensure the preload is up to standard and avoid overload or underload. Compared with welding or riveting, threaded connections do not require complex equipment and can be completed with just a wrench. They are suitable for mass production. After wear, only local parts such as bolts need to be replaced, without the need for overall structural repair. The core advantages of threaded tightening are its mechanical reliability, process controllability and application flexibility.
[0037] The length of the stop block 6 can be set to be the same as the width of the U-shaped seat 5, or it can be set to three times the width of the U-shaped seat 5.
[0038] The height of the first angle adjustment block 12a is set to three times that of the clamping seat 16 so as not to interfere with the hand saw cutting the object.
[0039] Example 2
[0040] like Figure 4 As shown in Embodiment 2 of this utility model, an angle-adjustable hand saw fixture includes: a base 4, a clamping seat 16 for clamping is fixed on the base 4 by bolts, a slot seat 11 is fixed on the base 4 by bolts, a second angle adjustment block 12b is movably inserted into the slot seat 11, one side of the second angle adjustment block 12b is a straight surface, and a second magnetic ring 10b is fixedly provided on the straight surface, and the bottom of the second angle adjustment block 12b is integrally formed with an insert block 15, which is movably inserted into the groove of the slot seat 11. One side of the second angle adjustment block 12b is in contact with one side of the clamping seat 16. The consumable plate 9 prevents the base 4 from being damaged during hand saw cutting and is easy to replace. When the hand saw is not in use, it can be attracted to the magnetic ring 10b.
[0041] By adjusting the first angle adjustment block 12a and the second angle adjustment block 12b, you can switch to another angle plane to provide leverage for the handsaw.
[0042] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
