Description

M270880 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a high-pressure constant-pressure vise, especially a mechanical pressure and constant-pressure structural device with high-pressure clamping and pressure setting. Functional high-pressure constant pressure tiger sweet structure improvement. [Previous technology] Traditional vise system uses the handle to turn the lead screw directly, and then drive the movable jaw on the vise, so that the movable jaw has an axial displacement clamping effect, but only by the spiral component force of the lead screw to produce the movable jaw. The clamping force is very limited, so the industry has proposed a hydraulic vise design in order to improve the clamping force of the vise (such as the new 8 1 2 0 4 6 3 3 "oil pressure "Vise patent" ^). However, this type of hydraulic vise leaks often occur. Not only the manufacturer is troubled by the after-sales service of the vise, but also the user often causes the job when the oil leakage is not enough to hold the work. Defects due to material displacement and looseness, and even caused the entire production operation to stall, and suffered a great loss. The reason is that the oil-type vice is caused by oil leakage. It is the vice about enhancing clamping force. The design still needs improvement. Secondly, the conventional vise does not have the function of clamping with a certain force. Therefore, it is applied to a large number of precision processing and production, especially for clamping softer work objects (such as copper and aluminum). When the user manually controls the lead screw and the clamping force of the movable jaw, the deformation amount of each work piece compressed by the vise clamping force is different. The finished work piece will have a dimensional error, especially with the tool. When the combination of abrasion errors occurs, it becomes more difficult to control the amount of errors.

A high-power constant-pressure vise (see picture 1). For the implementation of this creative application, please refer to the second and third figures. When the user places the work object 4 behind the fixed jaw 12 (that is, on the two slide rails 1 1 1), it can be used in advance on the slide handle. Adjust the position of the movable jaw 13 and the nut seat 1 4 on the Π 1, and then make the positioning member 15 penetrate the positioning hole 1 14 and the perforation 1 4 2 of the nut seat 14 to fix the ^ hai nut seat 14 and Make the movable jaw 1 3 slide at the fixing point of the nut seat 1 4 ®. If so, the user can rotate the scale ring 32 of the constant force mechanism 3 in advance to synchronously rotate the force setting ring 35, and use the fixed stop element 3 5 4 at the front end of the force setting ring 35 to change the rear end face of the second clutch ring 34. Cachi in different classes 3 4 3

Page 10 M270880 Fourth, the positioning groove 3 4 5 of the creative description (7) moves, so that the second clutch ring 3 4 can move forward and backward while maintaining a specific distance d from the first clutch ring 3 3 (see the sixth figure) As shown). If so, when the user turns a wrench (not shown) through the wrench sleeve 3 6 of the constant force mechanism 3, the driver screw 2 6 is first rotated (at this time, the second clutch ring 3 4, The force setting ring 3 5 and the scale ring 3 2 rotate synchronously without changing the distance d), and the double screw clutch ring 23, needle roller 24, double force ejector rod 25, double The top ring 22, the outer ring sleeve 21, and the female screw 16 are rotated, so that the female screw 16 is rotated to push the movable jaw 13 forward to reach the working object (as shown in the third figure). After the movable jaw 1 3 hits the work object (see figure 7), the user 0 continues to turn the wrench sleeve 3 6 with a wrench. Force clutch ring 2 3, needle roller 2 4, double force top rod 2 5, double force top ring 2 2, outer ring sleeve 2 1 and female screw 1 6 all stop rotating, and synchronously make the fixed stop element of the secondary screw 2 6 2 6 3 disengage from the positioning hole 2 3 4 and use the screw rod 2 6 outer thread section 2 6 4 to move forward and backward by the screw action, push the double force ejector rod 2 5 forward to push out the four rollers 2 4 and make four The roller pin 2 4 pushes the groove 2 2 3 of the double force top ring 2 2 and moves forward to push the push rod 20 and compresses the dish-shaped elastic element 2 2 4, so the push rod 2 0 can be used. The forward movement and the female screw 16 are pushed by the elastic element 2 2 4 to make the movable jaw 13 produce a high-power force to clamp the work piece 4 to prevent the movable jaw 13 from loosening due to the vibration of the cutting process. . However, the double-force clamping force of the high-power supercharging mechanism 2 described above can be set to a specific force due to the% force mechanism 3, which is caused by the fixed stop element 2 6 3 of the sub-screw 2 6 leaving the positioning hole 2 3 4 When pushing forward, push the synchronous wrench sleeve 3 6 to push the second clutch ring 34 forward (as shown in the seventh figure), the second clutch ring

Page 11 M270880 IV. Creative instructions (8) 3 4 When the sub-screw 2 6 rotates synchronously and is received by the wrench sleeve clutch ring 3 3 at the rear end, the oblique wedge 3 3 is caused by the first clutch ring 3 3 Because it is with the outer ring sleeve 2 1, the second clutch ring 3 4 can be locked, and the sub screw can be locked and stopped synchronously. Therefore, the sub screw 2 6 is restricted by the distance d before it can achieve a certain force. The effect of moving the jaw 1 3, and the user who obtains a fixed force can rotate the scale ring 3 2 arbitrarily, adjust the distance d between the clutch rings 3 3, and adjust the distance d by the lever d 2 5 (the opposite is the set push Rod 20) forward stroke • fixed force clamping function. Using this creation, the high-force constant-pressure vise consisting of the vise body 1 and the high-force mechanism 3 can be doubled and prevented from falling off, that is, it can be applied to the loosening of the female screw 16 or the movable jaw 13 of the work; It is specially designed to be consistent in the precision cutting force of a large number of the same workpieces, so it can prevent the variation of the workpieces, reduce the processing factor to the quality control of the tool when it is engaged in production, and improve the workpieces. Creation "High pressure determination and creativeness, and the use of its means are also in line with the new ten goals, which has been said to have progressed reasonably to the Ming patent application. However, I would like to ask Jun Bureau for detailed review to merit it." The barrel 3 6 pushes forward and moves to the first [, 3 4 1 engage with each other, this constitutes an integrated non-rotation state. The hand sleeve 3 6 is also the stroke of the rod 2 5 and the female screw 16 is visible, so that the rod 2 6 and Push and push the force to act on the function. From the second clutch ring 34 and the first set, the setting of further double force and its live weight cut is, when the shape and wear is accurate, the vise does nothing, and it is determined that the double force is reached to set the tiger supercharged mobile jaw 13 to cut. Processing and hunting should be determined because of its various parts, precision, "and it is suspected, and because of this, according to the quasi-special structure 2 miscarriage situation occurs twice, so it can be effective and effective. The anti-construction 3 force clip is easy to achieve. Practical and new prayers,
