Description

Technical Field

[0001] The invention belongs to the technical field of servo motors, and in particular relates to a servo motor which is convenient to install with a coupling. Background Art

[0002] Servo motors have the advantages of being able to control speed and have very accurate position accuracy, and can convert voltage signals into torque and speed to drive the controlled object. Servo motors are generally connected to driven equipment using couplings, among which diaphragm couplings are suitable for shaft transmission in high-temperature, high-speed, and corrosive media working environments, and can compensate for axial, radial, and angular offsets between the driving and driven machines caused by manufacturing errors, installation errors, load deformation, and temperature rise changes.

[0003] The diaphragm coupling is generally composed of an intermediate sleeve and two half sleeves. A diaphragm is arranged between the sleeves and fixed by bolts. During installation, the two half sleeves are firstly sleeved on the driven shaft and the motor output shaft respectively, and then the intermediate sleeve is placed between the two half sleeves and aligned, and finally the diaphragm is fixed by bolts.

[0004] When installing the diaphragm, multiple persons are required to hold the intermediate sleeve and the diaphragm respectively and tighten the bolts at the same time, which makes the installation of the diaphragm coupling inconvenient. Summary of the invention

[0005] The purpose of the present invention is to provide a servo motor which is convenient to install with a coupling. Through the cooperation of a limit frame, a support frame, a clamping frame and a clamping unit, after installing the half-axle sleeves on both sides, the support frame and the limit frame are used to clamp the half-axle sleeves, thereby limiting the height of the support frame, and placing the middle sleeve on the support frame.

[0011] It is further defined that the end of the second V-shaped frame away from the slider is fixedly connected to a vertical plate, and the clamping plate rests on the vertical plate.

[0029] like Figures 1 to 4 As shown, a servo motor that is convenient for installation with a coupling of the present invention includes a motor body 1 and an auxiliary installation component, the auxiliary installation component includes two limit frames 31 sleeved on the half-shaft sleeve 21 and a support frame 32 for supporting the intermediate shaft sleeve 22, a slide groove is vertically opened on the inner side of the limit frame 31, a clamping frame 33 is slidably installed in the slide groove of the limit frame 31, a mounting groove is opened on one side of the clamping frame 33 of the limit frame 31, a clamping unit 34 is arranged in the mounting groove of the limit frame 31, and the clamping unit 34 is used to clamp the clamping frame 33, a first connecting rod 35 is fixedly connected between the two clamping frames 33, and the support frame 32 is fixedly connected to the first connecting rod 35.

[0030] The limiting frame 31 includes a first V-shaped frame 311, a first plate 312 and a second plate 313. The first V-shaped frame 311 is placed on the upper end of the corresponding half-shaft sleeve 21. The first plate 312 and the second plate 313 are respectively fixedly connected to the two ends of the first V-shaped frame 311. The slide groove is arranged on the inner side of the first plate 312, and the mounting groove is arranged on the second plate 313. By arranging the first V-shaped frame 311, it is suitable for diaphragm couplings of different specifications.

[0031] The clamping frame 33 includes a second V-shaped frame 331 and a slider 332. The slider 332 is slidably installed in the slide groove. The second V-shaped frame 331 is fixedly connected to the slider 332 and abuts against the lower end of the corresponding half sleeve 21. By setting the second V-shaped frame 331, it is suitable for diaphragm couplings of different specifications.

[0032] The clamping unit 34 includes a fixing rod 341, which is fixedly connected in the installation groove, a clamping plate 342 is sleeved on the fixing rod 341, a rotating rod 343 is installed in the installation groove for transverse rotation, the clamping plate 342 is fixedly connected to the rotating rod 343, a clamping block 344 is fixedly connected above the clamping plate 342 of the fixing rod 341, and a compression spring 345 is arranged below the clamping plate 342 of the fixing rod 341. The second V-shaped frame 331 is tightened by the clamping plate 342, so that the height of the second V-shaped frame 331 remains unchanged, thereby limiting the height of the support frame 32, which is convenient for installing the intermediate sleeve 22 and the diaphragm.

[0033] The end of the second V-shaped frame 331 away from the slider 332 is fixedly connected with a vertical plate 333, and the clamping plate 342 leans against the vertical plate 333. By providing the vertical plate 333, the contact surface between the second V-shaped frame 331 and the clamping plate 342 is increased, and the application range of the second V-shaped frame 331 is expanded.

[0034] A pull frame 346 is fixedly connected between the two clamping plates 342. By arranging the pull frame 346, it is convenient to press down the clamping plates 342 on both sides so that the clamping plates 342 are separated from the vertical plate 333, and it is more convenient to disassemble the auxiliary installation assembly.

[0035] The support frame 32 includes a third V-shaped frame 321 and a rod body 322. The rod body 322 is fixedly connected to the first connecting rod 35.

By providing the third V-shaped frame 321, it is suitable for diaphragm couplings of different specifications.

[0036] A second connecting rod 314 is fixedly connected between the two first plates 312. The second connecting rod 314 is provided to combine the two first plates 312, so that the limiting frame 31 can be easily taken and disassembled.

[0037] The working principle and usage of this embodiment are as follows:

[0038] First, the two half-shaft sleeves 21 are respectively mounted on the output shaft and the driven shaft of the motor body 1 by using the key slots. When the auxiliary mounting assembly is not in use, the clamping frame 33 is located at the bottom of the slide slot. At this time, the clamping frame 33 and the limiting frame 31 form an opening, and the limiting frame 31 is mounted on the half-shaft sleeves 21 through the opening.

[0039] After the assembly of the limiting frame 31 is completed, the support frame 32 is lifted upward, and the support frame 32 drives the clamping frames 33 on both sides to rise until the clamping frames 33 contact the bottom of the half-axle sleeve 21. After the clamping frames 33 are released, the vertical plate 333 contacts the clamping plate 342 in the clamping unit. Due to the restriction of the clamping block 344, the clamping plate 342 will press against the vertical plate 333, so that the second V-shaped frame 331 cannot move downward, thereby fixing the position of the support frame 32;

[0040] After the support frame 32 is fixed, the intermediate sleeve 22 is placed on the support frame 32. At this time, the axes of the intermediate sleeve 22 and the half sleeve 21 are collinear, and the operator does not need to fix the intermediate sleeve 22 by hand, which facilitates the subsequent installation of the diaphragm and bolts.

[0041] The above is a detailed introduction to a servo motor that is convenient for installation with a coupling provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention.
