According to the processing equipment for processing the key groove on the spline shaft, firstly, the longitudinal section of the spline shaft 33 is matched with the longitudinal section formed by the clamping hole 6 and the anti-rotation bar, namely, the longitudinal section of the spline shaft 33 is similar to a gear shape, and the longitudinal section of the clamping hole 6 and the anti-rotation bar are in a shape matched with the gear shape, so that after the spline shaft 33 is inserted into the clamping hole 6, the spline shaft 33 cannot rotate in the processing process.
When the spline shaft 33 is machined, the driving block 2 drives the broach 3 to move, the broach 3 gradually and deeply cuts the lower side of the spline shaft 33 in a deep drawing mode in the moving process until the machining is completed, the driving block 2 and the broach 3 reversely move and reset, the spline shaft 33 is pulled out of the clamping hole 6, and then a new spline shaft 33 to be machined is inserted into the clamping hole 6. Wherein, a plurality of clamping holes 6 (two in the drawing and other numbers according to actual conditions) can be simultaneously formed on the positioning body 4, so that a plurality of spline shafts 33 can be processed at one time; secondly, when the spline shaft 33 is positioned, only the end part of the spline shaft 33 is inserted into the clamping hole 6, and the positioning is performed without using a complex clamp, so that the processing efficiency can be improved to a great extent; meanwhile, the clamping hole 6 and the anti-rotation bar can stably fix the position of the spline shaft 33, so that the fixing effect is good, and a processing instruction is ensured; and compared with the traditional milling cutter, when the broach 3 is adopted for processing, the processing of the key slot 34 can be completed only by moving the driving block 2 by one stroke, and the processing is simple and convenient, and meanwhile, the efficiency is higher.
It should be understood that the upper surface of the broach 3 has a plurality of rows of teeth, and the size and shape of each row of teeth increases and changes sequentially from the cutting end to the cutting end, so that the machining is shallow to deep, and deformation of the broach 3 is prevented. When the broach 3 performs a broaching motion, each tooth cuts a certain thickness of metal from the workpiece, resulting in the desired size and shape.
When the driving block 2 moves reciprocally, the driving block is limited by the two movable rails 7 at the same time, so that the motion stability of the driving block 2 and the broach 3 can be ensured; meanwhile, the driving cylinder 8 (preferably an oil cylinder, or an air cylinder or an electric push rod and the like can be selected according to actual conditions) is used as power for the reciprocating motion of the driving block 2. The same equipment can be replaced by different broaches 3, positioning bodies 4 and connecting pieces 9, so that different parts, such as anti-skid grooves on a transmission shaft, can be processed, and the investment and cost of the equipment can be saved.
When replacing different broaches 3 or performing similar processing on different workpieces, firstly, the connecting body 13 is taken out from the first connecting hole 10 upwards, and the connecting body 13 can be directly taken out because the connecting body 13 is not limited in the upward direction; after the connecting body 13 is separated from the connecting piece 9, the clamping groove 12 on the broach 3 is not limited by the clamping part 14 on the connecting body 13 in the direction away from the driving block 2, so that the broach 3 can be directly pulled out of the matching hole 11, and then the broach 3 of other types can be replaced for use, or the current broach 3 can be replaced (such as the current broach 3 is damaged).
When a new broach 3 is replaced, firstly, the end part of the broach 3 passes through the matching hole 11, and the end part of the broach 3 is abutted against the inner wall of the first connecting hole 10, which is close to the driving block 2; then, the connecting body 13 is clamped into the first connecting hole 10 downwards until the middle part of the connecting body 13 abuts against the upper surface of the broach 3, and the connecting body 13 cannot be lowered continuously. Wherein the engaging portion 14 is engaged in the engaging groove 12 in the horizontal direction, so that the broach 3 and the connecting body 13 are kept relatively stable in the horizontal direction; then, since both the X-direction and Y-direction sides of the connecting body 13 in the horizontal direction are abutted against the inner wall of the first connecting hole 10, the connecting body 13 and the connecting piece 9 are kept relatively stable, so that when the connecting piece 9 is moving, the broach 3 and the connecting piece 9 are kept moving in a quite synchronous manner, and the processing stability is ensured. Moreover, two clamping grooves 12 are formed in two sides of the broach 3, and two clamping portions 14 are formed in two sides of the connecting body 13, so that acting force for driving the broach 3 to move can be shared, and meanwhile, the position stability of the broach 3 can be better guaranteed.
Furthermore, if the entire connecting member 9 is to be replaced, and then a new broach 3 is to be replaced or a new work piece is to be processed (also, for example, when a new positioning body 4, a new broach 3 and a new connecting member 9 are to be replaced in the case of processing an anti-slip groove on a transmission shaft), the connecting cap 16 is first rotated in the operation hole 17, and the connecting cap 16 is separated from the connecting post 15, and then the connecting member 9 can be directly removed from the driving block 2; when a new connecting piece 9 is replaced (a new matching hole 11 is formed in the new connecting piece 9, a new connecting body 13 is needed to be used, such as machining of a transmission shaft), the connecting column 15 of the new connecting piece 9 only needs to pass through the dismounting hole 18, then the angle of the connecting piece 9 is adjusted to be suitable (the top of the connecting piece 9 is generally horizontal, the angle of the connecting piece 9 can be adjusted to be suitable through a simple level meter), and the connecting cap 16 is screwed down, so that the connecting cap 16 and the connecting piece 9 are clamped on the driving block 2, and the replacement of the connecting piece 9 is realized.
Typically, when processing different workpieces, the positioning body 4 needs to be replaced at the same time; when the connecting part is replaced, the positioning screw 23 is rotated firstly, so that the positioning screw 23 is separated from the positioning plane 22, and then the connecting part 4b can be directly pulled out of the second connecting hole 20 in the direction away from the driving block 2; then when the new positioning body 4 is replaced, only the connecting part 4b of the new positioning body 4 is needed to be inserted into the second connecting hole 20, and then the positioning screw 23 is rotated to enable the positioning screw 23 to be abutted to the positioning plane 22 at the top, so that the positioning device is simple and convenient.
Wherein, the four directions of the connecting part 4b are provided with positioning planes 22, so that the connecting part 4b is convenient to be clamped into the second connecting hole 20; next, except that the four positioning planes 22 are planes, the outer wall of the connecting portion 4b between two adjacent positioning planes 22 is arc-shaped, so that the arc-shaped portion is round, and after the connecting plate 19 is connected, the round arc-shaped portion is attached to the inner wall of the second connecting hole 20, so that the connection stability between the connecting plate 19 and the positioning body 4 can be better improved. When the connecting portion 4b is inserted into the second connecting hole 20, the position of the connecting portion 4b is indicated to be proper when the stabilizing ring 21 is abutted against the connecting plate 19, then the angle of the positioning body 4 is also proper by a simple level instrument or other tools, and finally the angle of the connecting portion 4b is fixed after the positioning screw 23 is abutted against the positioning plane 22 at the top, so that the machining process can be stably performed. Meanwhile, when the broach 3 is used for machining, the workpiece and the positioning body 4 are acted on by the acting force in the direction close to the driving block 2, and at the moment, the whole positioning body 4 is abutted on the connecting plate 19 through the stabilizing ring 21, so that the position of the positioning body 4 can be well ensured, and the positioning body 4 is prevented from moving in position.
During the processing, the cooling liquid flows out of the cooling pipe 25, and can act on the broach 3 and the spline shaft 33 after entering the cooling hole 24, so that the cooling effect can be achieved, the lubricating effect can be achieved, the processing can be performed with high quality, and meanwhile, the equipment and the workpiece are protected. The bottom of the abdication hole 5 is provided with the wear-resisting block 26, so that the broach 3 can be better prevented from grinding the abdication hole 5 more and more, and the stable maintenance of the machining depth of the broach 3 is ensured. The use time is increased, so that the new broach 3 can be replaced, and the abrasion-resistant block 26 also needs to be replaced periodically (although the replacement frequency is lower); when the wear-resistant block 26 is replaced, the wear-resistant block 26 can be removed simply and conveniently only by removing the fixing screw 27 and separating the top of the fixing screw 27 from the groove at the bottom of the wear-resistant block 26. After the new wear-resistant block 26 is replaced, the fixing screw 27 and the inner wall of the yielding hole 5 can better ensure the position stability of the wear-resistant block 26, wherein the groove on the wear-resistant block 26 does not penetrate out of the top of the wear-resistant block 26, namely the top of the wear-resistant block 26 is planar, so that the abrasion between the broach 3 and the wear-resistant block 26 can be better reduced.
When the spline shaft 33 is inserted into the clamping hole 6 from one end, until the other end of the spline shaft 33 abuts against the adjusting rod 32, that is, the position of the spline shaft 33 is properly reached, at this time, the spline shaft 33 cannot rotate, and the position in the horizontal direction is stable. In the actual machining process, the positions of the different workpieces to be machined will also have different differences, and at this time, the depth of the adjusting rod 32 extending into the clamping hole 6 needs to be changed, that is, the greater the depth of the end of the adjusting rod 32 extending into the clamping hole 6, the closer the machined place on the spline shaft 33 is to the end of the spline shaft 33, the smaller the depth of the end of the adjusting rod 32 extending into the clamping hole 6, the farther the machined place on the spline shaft 33 is from the end of the spline shaft 33. Thus, different spline shafts 33 or other workpieces can be machined through the adjusting rod 32, and applicability is improved.
The adjusting screw 28, the anti-falling block 29 and the adjusting ring 31 enable a certain gap to be formed between the adjusting plate 30 and the positioning portion 4a, so that the larger the adjusting range of the adjusting rod 32 is (i.e. if the adjusting plate 30 is directly attached to the positioning portion 4a, the largest moving range of the spline shaft 33 is abutted to the adjusting plate 30), and the application range is further enlarged; furthermore, in actual use, the distance between the adjusting plate 30 and the positioning portion 4a can be further adjusted by replacing the adjusting rings 31 with different thicknesses, so that the application range is further enlarged.
