Detailed Description
Referring to the attached figures 1-3, a tool for a reducer short shaft key groove and a plane comprises a base 1, vertical plates 2, clamping grooves 3, a pressing plate 4, a screw rod 5 and a nut 6, wherein the vertical plates 2 are respectively vertically arranged at the front end and the rear end of the upper surface of the base 1, a plurality of clamping grooves 3 are arranged on the vertical plates 2, the clamping grooves 31 with odd numbers from left to right are large semicircular grooves, the positions of the right upper corners of the clamping grooves are provided with arc-shaped openings, the clamping grooves 32 with even numbers from left to right are large semicircular grooves, the positions of the left upper corners of the clamping grooves are provided with arc-shaped openings, the clamping grooves 31 with odd numbers on the left side, and the arc-shaped opening of each odd number of clamping grooves 31 and the arc-shaped opening of each even number of clamping grooves 32 are communicated to form a boss, a screw rod 5 is designed on the boss, a through hole is formed in the middle of the pressing plate 4, the pressing plate 4 is sleeved on the screw rod 5 through the through hole, and a nut 6 is designed on the pressing plate 4 and screwed on the screw rod 5. The lead screw and nut may be replaced with a screw.
The base 1 and the vertical plate 2 are integrally cast and molded.
Arc-shaped grooves 41 are respectively designed on two sides of the lower end of the pressure plate 4. The arc-shaped groove and the large semicircular groove of the clamping groove are matched to form a similar circular structure, and are matched with each other to effectively clamp the short shaft workpiece.
Two ends of the pressing plate 4 are positioned between two adjacent clamping grooves, and the end parts of the two ends of the pressing plate and the upper end openings of the clamping grooves on the two sides form a processing opening 7.
A spring 9 is further arranged between the pressing plate 4 and the boss and sleeved on the screw rod, spring grooves are formed in the middle of the lower end of the pressing plate and the middle of the upper end of the boss respectively, and the spring 9 is located in the two spring grooves. When the nut is loosened, the spring directly jacks up the pressing plate, so that short shaft workpieces are convenient to take out.
A positioning cylinder 8 is designed on the inner side of each clamping groove 3, the positioning cylinder 8 is installed on the base and used for assisting installation of short shaft type workpieces, the short shaft type workpieces are inserted into the clamping grooves from the outer sides, and the front ends of the short shaft type workpieces are propped against the positioning cylinders, so that the situation is in place and the operation is rapid; the positioning column is not designed, and then an installer needs to perform visual positioning through the structure of the short shaft type workpiece.
When the utility model is used, the nut is loosened, the short shaft type workpieces are inserted into the slot holes from the outer sides of the clamping slots, the adjacent left odd clamping slots and right even clamping slots of each group are simultaneously inserted into the short shaft type workpieces, through positioning by a positioning cylinder or positioning by visual inspection of the insertion depth of the structure of the workpiece, the arc-shaped grooves on the two sides of the lower end of the pressing block are respectively matched with the odd-numbered clamping grooves on the left side and the even-numbered clamping grooves on the right side to clamp the short-shaft workpieces, then the nut is locked to enable the pressing block to tightly press the short shaft type workpieces, the operation is carried out in sequence, each group of the rest of the operation handles is clamped with the short shaft type workpieces, a machining opening is formed by a distance between the pressing block and the clamping groove, when the short shaft type workpieces are machined into key grooves or planes, the stress positions of the short shaft type workpieces are located at the machining opening, therefore, the short shaft workpieces are not easy to move, the machining precision is guaranteed, a plurality of workpieces are clamped at one time, the clamping time is saved, and the production efficiency is improved.
