[0001] The utility model relates to the technical field of resolver transmitters, and particularly relates to a resolver transmitter convenient for maintenance. Background Technique

[0002] As a position sensor using the principle of electromagnetic induction, the resolver transmitter can achieve a position accuracy of up to angular minutes or even angular seconds and can meet the usage requirements of speeds of tens of thousands of revolutions. Therefore, the brushless resolver transmitter can rival the commonly used angle position sensors in terms of performance indicators; it has the advantages of strong anti-vibration and impact resistance, and strong anti-electromagnetic interference ability. When the resolver transmitter is used for a long time, it is necessary to regularly maintain the resolver transmitter to ensure its normal operation. When performing maintenance work, it is necessary to repair and replace the resolver transmitter according to the actual situation. Therefore, a resolver transmitter convenient for maintenance is needed.

[0003] However, the existing resolver transmitter has weak maintenance functions, and the work of maintaining the transmitter during the maintenance process is rather cumbersome, which affects the maintenance efficiency. Moreover, the existing resolver transmitter has a poor fixing effect, and during the operation of the transmitter, the position of the transmitter is prone to shift, resulting in the difficulty of the transmitter to work normally. Content of the Utility Model

[0004] The purpose of the utility model is to provide a resolver transmitter convenient for maintenance to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A resolver transmitter convenient for maintenance includes a fixing plate. Fixing holes are opened at the four corners of the top of the fixing plate, and fixing bolts are threadedly connected inside the fixing holes. Connecting frames are fixedly connected to both sides of the top of the fixing plate. A hollow frame is fixedly connected to one side of the connecting frame. A hollow column is fixedly connected to the middle of the surface of the hollow frame. A connecting hole is opened at one end of the hollow column, and a connecting component is threadedly connected inside the connecting hole. A bearing component is movably connected to one side of the surface of the connecting component. A limiting component is fixedly connected to the top of the bearing component.

[0010] Preferably, a circular hole is formed on one side of one of the protection plates, and one side of the circular hole is movably connected to one side of the surface of the resolver transmitter body.

[0011] Preferably, a connecting groove is formed at the top end of the connecting frame, and one side of the connecting plate is movably connected inside the connecting groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. For this resolver transmitter that is convenient for maintenance, through the settings of the connection assembly, connection frame, housing, bearing assembly and limiting assembly, when in use, the connection bolt on one side of the hollow column can be rotated, and the connection bolt drives the connection block to move under the cooperation of the connection frame, and then the connecting plate at the bottom end of the rectangular plate is taken out of the connection frame by using the bearing plate. Then, press the multiple limiting blocks protruding outside the limiting plate, so that the limiting blocks compress the limiting springs in the limiting rods and part of the limiting blocks are retracted into the limiting rods. Then, use the two protection plates to take out the four limiting rods from the limiting plate, and then take out the resolver transmitter body, so as to maintain and replace the resolver transmitter body, achieving the effect of being convenient for maintenance and improving work efficiency.

[0014] 2. For this resolver transmitter that is convenient for maintenance, through the settings of the fixing plate, fixing bolt, connection frame, hollow frame, hollow column, connection assembly and bearing assembly, after the maintenance is completed, a new resolver transmitter body can be placed in the housing. Then, press the limiting blocks outside the limiting rods, so that the limiting blocks compress the limiting springs in the limiting rods and part of the limiting blocks are retracted into the limiting rods. Then, use the protection plates to insert the multiple limiting rods into the limiting plate. When reaching the appropriate position, the limiting springs push out the limiting blocks, and the positions between the limiting rods and the limiting plate are fixed by using the limiting blocks. Then, use the bearing plate to insert the connecting plate connected to the bottom end of the rectangular plate into the connection frame, and then rotate the connection bolt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 as shown, a technical solution provided by the present utility model:

[0022] A resolver transmitter convenient for maintenance, including a fixing plate 1. Fixing holes are provided at the four corners of the top of the fixing plate 1. Fixing bolts 2 are threadedly connected inside the fixing holes. Connecting frames 3 are fixedly connected to both sides of the top of the fixing plate 1. A hollow frame 4 is fixedly connected to one side of the connecting frame 3. A hollow column 5 is fixedly connected to the middle of the surface of the hollow frame 4. A connecting hole is provided at one end of the hollow column 5. A connection component 6 is threadedly connected inside the connecting hole. A bearing component 7 is movably connected to one side of the surface of the connection component 6. A limiting component 8 is fixedly connected to the top of the bearing component 7. A housing 9 is fixedly connected to the top of the limiting component 8. A resolver transmitter body 10 is movably connected inside the housing 9;

[0023] Specifically, the fixing bolt 2 can be used to fix the fixing plate 1 in a suitable position. Then, the hollow frame 4 can be used to install the connecting plate 701, and the hollow column 5 is used in cooperation with the connecting bolt 601 to connect the hollow frame 4 and the connecting plate 701;

[0024] It can be understood that the connecting plate 701 is inserted into the hollow frame 4, and then the connecting bolt 601 is rotated. With the cooperation of the hollow column 5, the position of the connecting plate 701 is fixed by the connecting block 605;

[0025] In this embodiment, preferably, the connecting component 6 includes a connecting bolt 601. One side of the surface of the connecting bolt 601 is threadedly connected to the connecting hole opened at one end of the hollow column 5. One end of the connecting bolt 601 is fixedly connected to a connecting piece 602. One side of the connecting piece 602 is fixedly connected to a column body 603. A telescopic spring 604 is sleeved on the surface of the column body 603. One end of the column body 603 is fixedly connected to a connecting block 605;

[0026] Specifically, when the connecting bolt 601 is rotated, the connecting bolt 601 drives the connecting block 605 to insert into the connecting plate 701, and at the same time, the telescopic spring 604 on the column body 603 is compressed by using the connecting piece 602 in cooperation with the hollow column 5. When the connecting frame 3 is fixed to the connecting plate 701, the telescopic spring 604 will generate a reaction force on the connecting piece 602, thereby reducing the possibility of the connecting bolt 601 loosening;

[0027] It can be understood that when the connecting bolt 601 drives the connecting block 605 to move, the distance between the connecting piece 602 and the hollow column 5 is reduced, thereby compressing the telescopic spring 604 on the column body 603. The resilience generated when the telescopic spring 604 is compressed will be transmitted to the connecting bolt 601 through the connecting piece 602, increasing the friction between the connecting bolt 601 and the hollow column 5, thereby reducing the loosening of the connecting bolt 601;

[0028] In this embodiment, preferably, the bearing component 7 includes a connecting plate 701. One end of the connecting plate 701 is movably connected to one side of the surface of the connecting block 605. The top end of the connecting plate 701 is fixedly connected to a rectangular plate 702. One end of the rectangular plate 702 is fixedly connected to a bearing plate 703;

[0029] Specifically, the bearing plate 703 is used to insert the connecting plate 701 connected to the bottom end of the rectangular plate 702 into the connecting frame 3;

[0030] It can be understood that after the connecting plate 701 is fixed to the connecting frame 3, the rectangular plate 702 at the top end of the connecting plate 701 is also fixed, thereby fixing the bearing plate 703 on the fixing plate 1;

[0031] In this embodiment, preferably, the limit component 8 includes a limit plate 801. The bottom end of the limit plate 801 is fixedly connected to the top end of the bearing plate 703. Two limit grooves are formed on both sides of the limit plate 801. A limit rod 802 is movably connected inside the limit groove. A limit spring 803 is fixedly connected inside the limit rod 802. One end of the limit spring 803 is fixedly connected to a limit block 804. One end of the limit rod 802 is fixedly connected to a protection plate 805;

[0032] Specifically, press the limit block 804 outside the limit rod 802 to compress the limit spring 803 inside the limit rod 802 and make part of the limit block 804 retract into the limit rod 802. Then, use the protection plate 805 to insert multiple limit rods 802 into the limit plate 801. When reaching the appropriate position, the limit spring 803 will push out the limit block 804, and use the limit block 804 to fix the position between the limit rod 802 and the limit plate 801;

[0033] It can be understood that the position of the limit block 804 is controlled by the limit spring 803, so as to install and disassemble between the limit rod 802 and the limit plate 801;

[0034] In this embodiment, preferably, a round hole is formed on one side of one of the protection plates 805, and one side of the round hole is movably connected to one side of the surface of the resolver transmitter body 10;

[0035] In this embodiment, preferably, press the limit block 804 outside the limit rod 802 to compress the limit spring 803 inside the limit rod 802 and make part of the limit block 804 retract into the limit rod 802. Then, use the protection plate 805 to insert multiple limit rods 802 into the limit plate 801. When reaching the appropriate position, the limit spring 803 will push out the limit block 804, and use the limit block 804 to fix the position between the limit rod 802 and the limit plate 801.

[0036] When a resolver transmitter that is convenient for maintenance in this embodiment is in use, the fixing plate 1 can be fixed in a suitable position by using the fixing bolts 2. Then, the resolver transmitter main body 10 is placed in the housing 9. Then, the limiting block 804 outside the limiting rod 802 is pressed, so that the limiting block 804 compresses the limiting spring 803 inside the limiting rod 802 and part of the limiting block 804 is received into the limiting rod 802. Then, the protection plate 805 is used to insert multiple limiting rods 802 into the limiting plate 801. When reaching the appropriate position, the limiting spring 803 ejects the limiting block 804, and the position between the limiting rod 802 and the limiting plate 801 is fixed by using the limiting block 804. Then, the connecting plate 701 connected to the bottom end of the rectangular plate 702 is inserted into the connecting frame 3 by using the bearing plate 703. Then, the connecting bolt 601 is rotated, so that while the connecting bolt 601 drives the connecting block 605 to insert into the connecting plate 701, the connecting piece 602 cooperates with the hollow column 5 to compress the telescopic spring 604 on the column body 603. When the connecting frame 3 and the connecting plate 701 are fixed, the telescopic spring 604 will generate a reaction force on the connecting piece 602, thereby reducing the possibility of the connecting bolt 601 loosening. During maintenance, the connecting bolt 601 on one side of the hollow column 5 can be rotated, so that the connecting bolt 601 drives the connecting block 605 to move under the cooperation of the connecting frame 3. Then, the connecting plate 701 at the bottom end of the rectangular plate 702 is taken out of the connecting frame 3 by using the bearing plate 703. Then, the multiple limiting blocks 804 protruding outside the limiting plate 801 are pressed, so that the limiting block 804 compresses the limiting spring 803 inside the limiting rod 802 and part of the limiting block 804 is received into the limiting rod 802. Then, the four limiting rods 802 are taken out of the limiting plate 801 by using two protection plates 805. Then, the resolver transmitter main body 10 is taken out, so as to maintain and replace the resolver transmitter main body 10.
