DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1-7A shaft parts processing equipment comprises a circular base 1, a fixed shaft 2 is installed at the center of the circular base 1 in a vertical state, the outer wall of the fixed shaft 2 is sleeved with three sleeves 31 in sequence, the outer wall of each sleeve 31 is welded with a connecting arm 32 extending outward, and each connecting arm 32 is rotatably connected to a driving arm 33 on a side away from the sleeve 31. The three driving arms 33 are evenly arranged in the circumferential direction, and all three are rotatably connected to the outer wall of a chuck 4 through a shaft. The shaft is fixed by the chuck 4 during tooling. This fixing method is a prior art and will not be described in detail in this application. By controlling each sleeve 31 to move in a fixed The shaft 2 rotates, so that the connecting arm 32 drives the driving arm 33 to move, which can drive the chuck 4 to realize the tilt adjustment in three-dimensional space, thereby realizing the multi-free adjustment of the shaft, solving the problem of limited angle adjustment range of the traditional chuck 4, and is particularly suitable for clamping and processing special-shaped shafts. When the three sleeves 31 are rotated at the same time, the three driving arms 33 will generate forces in the same linear direction. At this time, the chuck 4 performs pure rotational motion around its own axis under the action of the three-point synchronous torque without changing its spatial tilt angle, that is, the adjustment of the angle of the chuck 4 will not affect the rotation processing of the shaft, thereby ensuring the continuity and stability of the processing process.

[0031] The diameters of the three sleeves 31 increase from left to right, and the second sleeve 31 is sleeved on the outer wall of the first sleeve 31, and the two are connected in relative rotation. The third sleeve 31 is sleeved on the outer wall of the second sleeve 31, and the length of the sleeve 31 decreases from left to right, so that when the second sleeve 31 is sleeved on the outer wall of the first sleeve 31, the end does not exceed the end of the first sleeve 31, and when the third sleeve 31 is sleeved on the outer wall of the second sleeve 31, the end does not exceed the end of the second sleeve 31. The three sleeves 31 adopt a stepped nested structure, which effectively reduces the occupancy of the equipment in the length direction while ensuring that each sleeve 31 rotates independently, making the overall equipment more compact and small.

[0032] Three motors 5 are circumferentially arranged on the base 1, and driving gears 6 are arranged at the output ends of the three motors 5. Driven gears 34 cooperating with the driving gears 6 are respectively arranged on the side of the three sleeves 31 facing the motor 5. Each driven gear 34 is meshed and connected with the corresponding driving gear 6 to control the rotation of the sleeve 31. Each motor 5 controls the rotation of a sleeve 31 separately, and the three motors 5 cooperate to control the rotation of the chuck 4, thereby realizing precise and flexible control over the shaft processing process and greatly improving the processing efficiency and flexibility.

[0033] A plurality of mounting grooves are provided on the circumference of the base 1. The mounting grooves are in an arc-shaped structure, and the entire device can be quickly adapted and installed on the workbenches of different machine tools in conjunction with T-shaped bolts.

[0034] A plurality of sliding blocks 41 that can move toward the center are circumferentially provided on the working surface of the chuck 4. The specific control process belongs to the prior art and will not be described in detail in this application. The sliding block 41 is an L-shaped structure as a whole, and a receiving groove that can accommodate a clamping arm 42 is provided on a side wall perpendicular to the chuck 4. The clamping arm 42 is rotatably connected in the receiving groove and can swing within the receiving groove by ±15°. A pair of clamping claws 43 are provided on the side of the clamping arm 42 away from the sliding block 41 to form multi-point clamping of the shaft. When the clamping claws 43 clamp the end of an irregular shaft, the clamping arm 42 rotates in the sliding block 41, so that multiple clamping claws 43 clamp multiple points of the shaft to fix multiple points on the outer wall of the irregular shaft, thereby ensuring the stability of the clamping of the irregular shaft.

[0035] A slide groove 421 for a pair of sliders 422 to slide is provided in the clamping arm 42, and a rotatable screw rod 423 is provided in the slide groove 421. The screw rod 423 passes through the clamping arm 42 and a handwheel is provided at one end thereof to control the rotation of the screw rod 423. The screw rod 423 passes through a pair of sliders 422 and forms a threaded connection therewith. Each slider 422 is respectively connected to a clamping jaw 43 to control the relative position of the two clamping jaws 43. When the screw rod 423 is rotated, the two sliders 422 move in opposite directions toward each other on the outer wall of the screw rod 423. At this time, the distance between the two clamping jaws 43 connected to the two sliders 422 will change, which is convenient for clamping irregular shafts of different models, thereby greatly improving the adaptability of the device.

[0036] The clamping jaw 43 includes an inner jaw 431 and an outer jaw 432. The outer jaw 432 is detachably mounted on the outside of the inner jaw 431. One side of the inner jaw 431 is connected to the slider 422. By replacing the outer jaw 432 or adjusting the position of the outer jaw 432 on the inner jaw 431, the initial position of the end of the outer jaw 432 can be changed, so as to further adapt to the clamping of irregular shafts of different models.

[0037] The outer claw 432 is provided with two narrow grooves 433 penetrating the upper and lower walls and the side walls thereof, and an upper and lower extrusion plate 434 is formed between the two narrow grooves 433. The extrusion plate 434 has a certain elasticity and can be relatively deflected. The inner claw 431 is arranged between the upper and lower extrusion plates 434 to facilitate the extrusion plate 434 to fix the inner claw 431. The upper and lower extrusion plates 434 are provided with through holes 435. The inner claw 431 is provided with a strip-shaped through groove 436 matching the upper and lower through holes 435 to match the bolt and nut to form The outer jaw 432 and the inner jaw 431 are relatively fixed. The loose nut can pull or push the outer jaw 432 to change the position of the outer jaw 432 on the inner jaw 431. After the position adjustment of the outer jaw 432 is completed, the nut is tightened. At this time, the upper and lower extrusion plates 434 can clamp and fix the inner jaw 431, which greatly simplifies the adjustment process of the clamp 43, allowing the operator to quickly and accurately configure the clamp 43 to meet the processing requirements of different shaft parts, thereby improving work efficiency and convenience of operation.
