Description

Technical fields:

[0001] This utility model relates to the field of permanent magnet synchronous servo motor assembly technology, specifically to an auxiliary tooling for rapid assembly of a permanent magnet synchronous servo motor. Background technology:

[0002] Currently, the assembly of permanent magnet synchronous servo motors is mainly done manually. During actual assembly, due to the very small magnetic gap between the stator and rotor of the permanent magnet synchronous servo motor (typically 2-3 mm), and the presence of magnets (strong magnets) on the rotor, the stator and rotor are easily attracted together by magnetic force, causing installation quality and safety accidents. Furthermore, the assembly is difficult, severely impacting assembly speed and quality. Therefore, it is necessary to design a dedicated assembly fixture for permanent magnet synchronous servo motors based on actual production needs, aiming to reduce labor intensity and improve assembly accuracy and efficiency.

[0003] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content:

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide an auxiliary tooling for the rapid assembly of permanent magnet synchronous servo motors, which has the advantages of reasonable structural design, low labor intensity, high assembly accuracy and high assembly efficiency.

[0005] This utility model achieves the above objectives by adopting the following technical solutions:

[0006] An auxiliary tooling for quick assembly of a permanent magnet synchronous servo motor includes a support base with two support frames spaced apart on the base. Each support frame has a height-adjustable lifting plate, one of which has a chuck and the other has a positioning and tightening mechanism. The chuck and the positioning and tightening mechanism cooperate to suspend and fix the rotor assembly. A guide rail is provided on the support base between the two support frames, and a slider is provided on the guide rail. The slider has a slide block, and the slide block has multiple mounting holes for mounting the housing. The housing contains the stator assembly.

[0007] The support base includes two longitudinally spaced crossbeams, with longitudinal beams connected to the ends of the two crossbeams, and the guide rail is mounted on the crossbeams.

[0008] The support frame includes a support base plate mounted on a support base, a support upright plate vertically mounted on the support base plate, a reinforcing rib plate between the support upright plate and the support base plate, two adjusting nuts spaced apart at the upper end of the support upright plate, an clearance opening at the center of the support upright plate, two mounting plates spaced apart at the upper end of the lifting adjustment plate, and adjusting screws mounted on the mounting plates, with the lower ends of the adjusting screws mounted on the adjusting nuts.

[0009] The lifting adjustment plate is provided with guide slopes A on both sides, and two guide blocks are provided at intervals on the corresponding support plate. The guide blocks are provided with guide slopes B that cooperate with guide slopes A.

[0010] The support plate is provided with a plurality of waist-shaped holes at even intervals, and a locking screw is provided on the waist-shaped hole. The corresponding lifting adjustment plate is provided with a locking thread hole, and the locking screw is installed on the locking thread hole.

[0011] The chuck is designed as a four-jaw chuck.

[0012] The positioning and tightening mechanism includes a positioning support frame disposed inside the lifting and adjusting plate, a positioning sleeve slidably disposed at the center of the positioning support frame, a cylinder seat disposed outside the lifting and adjusting plate, a tightening cylinder disposed on the cylinder seat, the piston rod of the tightening cylinder being connected to the rear end of the positioning sleeve, and the front end of the positioning sleeve being connected to the docking rod.

[0013] The support base has multiple clamping buckles spaced apart on its side wall, and each clamping buckle is equipped with a clamping nut and a clamping screw.

[0014] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0015] The motor rotor assembly is suspended and fixed in the air using a chuck that can be adjusted up and down on one side and a positioning and clamping mechanism on the other side. Then, the stator and housing are directly fixed onto a movable slide. By pushing this slide, the stator can be moved to the position corresponding to the rotor.

[0026] like Figure 1-5As shown, an auxiliary tooling for quick assembly of a permanent magnet synchronous servo motor includes a support base 1, on which two support frames 2 are spaced apart. Each support frame 2 has a height-adjustable lifting plate 3. One lifting plate 3 has a chuck 4, and the other lifting plate 3 has a positioning and tightening mechanism 5. The chuck 4 and the positioning and tightening mechanism 5 cooperate to suspend and fix the rotor assembly 12. A guide rail 6 is provided on the support base 1 between the two support frames 2. A slider 7 is provided on the guide rail 6. A slide block 8 is provided on the slider 7. The slide block 8 has multiple mounting holes 9 for mounting the housing 10. The housing 10 contains a stator assembly 11. The rotor assembly 12 of the motor is suspended and fixed in the air by a chuck 4 that can be adjusted up and down on one side and a positioning and clamping mechanism 5 on the other side. Then, the stator assembly 11 and the housing 10 are directly fixed to a movable slide 8. By pushing the slide 8, the stator assembly 11 can be moved to a position corresponding to the rotor assembly 12. Finally, the front and rear flanges are installed, completing the positioning and assembly. This tooling can achieve relative axial and radial positioning of the rotor assembly 12 and the stator assembly, eliminating concerns about the stator and rotor sticking together and causing assembly and quality accidents, and greatly improving the assembly speed.

[0027] The support base 1 includes two longitudinally spaced crossbeams 101, with longitudinal beams 102 connected to the ends of the two crossbeams 101. The guide rail 6 is mounted on the crossbeams 101. It can be constructed by welding I-beams, resulting in a robust and reliable structure.

[0028] The support frame 2 includes a support base plate 201 mounted on a support base 1. A support upright plate 202 is vertically mounted on the support base plate 201. A reinforcing rib plate 203 is provided between the support upright plate 202 and the support base plate 201. Two adjusting nuts 204 are spaced apart at the upper end of the support upright plate 202. An clearance opening 205 is provided at the center of the support upright plate 202. Two mounting plates 13 are spaced apart at the upper end of the lifting adjustment plate 3. Adjusting screws 14 are provided on the mounting plates 13, and the lower ends of the adjusting screws 14 are mounted on the adjusting nuts 204. The specific lifting adjustment structure of the lifting adjustment plate 3 is provided, which can meet the assembly requirements of permanent magnet synchronous servo motors of different sizes.

[0029] The lifting and adjusting plate 3 has guide slopes A15 on both sides, and the corresponding support plate 202 has two guide blocks 16 spaced apart. The guide blocks 16 have guide slopes B17 that cooperate with the guide slopes A15. This guides the lifting and lowering of the lifting and adjusting plate 3.

[0030] The support plate 202 has a plurality of evenly spaced oblong holes 18, each with a locking screw 19. The corresponding lifting adjustment plate 3 has a locking threaded hole 20, and the locking screw 19 is installed in the locking threaded hole 20. This assists in locking the lifting adjustment plate 3, ensuring that it can be securely and reliably locked after its position is adjusted.

[0031] The chuck 4 is designed as a four-jaw chuck. The four-jaw chuck has the advantages of high reliability, compact structure and easy use, and is particularly suitable for positioning and clamping the rotor assembly 12.

[0032] The positioning and tightening mechanism 5 includes a positioning support frame 501 disposed inside the lifting and adjusting plate 3. A positioning sleeve 502 is slidably disposed at the center of the positioning support frame 501. A cylinder seat 503 is disposed outside the lifting and adjusting plate 3. A tightening cylinder 504 is disposed on the cylinder seat 503. The piston rod of the tightening cylinder 504 is connected to the rear end of the positioning sleeve 502. The front end of the positioning sleeve 502 is connected to the docking rod 505. The specific structure of the positioning and tightening mechanism 5 is given, which cooperates with the chuck 4 to achieve the suspension and fixation of the rotor assembly.

[0033] The support base 1 has multiple clamping buckles 21 spaced apart on its side wall. Each clamping buckle 21 is equipped with a clamping nut 22 and a clamping screw 23. This not only clamps the slide block 8, but also adjusts the height of the clamping screw 23 when the sliding clearance is too large, causing uneven gaps between the stator and rotor that affect assembly.

[0034] Instructions for use of the auxiliary tooling in this application:

[0035] First, adjust the height of the lifting adjustment plate 3 according to the size of the permanent magnet synchronous servo motor. After the height adjustment is completed, first install the housing 10 and the stator assembly 11 on the slide 8. Then, install one end of the shaft on the rotor assembly 12 (on which the front flange end cover 24 is installed) on the chuck 4, and connect the other end to the docking push rod 505 (on which the rear flange end cover 25 is pre-installed) that passes through the stator assembly 11, and tighten it with the clamping cylinder 504. Then, move the stator assembly 11 to the position corresponding to the rotor assembly 12 by pushing the slide 8. Finally, install the front flange end cover 24 and the rear flange end cover 25 to complete the positioning and assembly of the motor.

[0036] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0037] Any aspects of this utility model not described in detail are known to those skilled in the art.
