[0004] To achieve the above objectives, this utility model provides a tooling fixing plate for motor calibration. The motor includes a motor body and a drive shaft. The motor body has multiple mounting holes. The tooling fixing plate includes:

[0005] The fixed plate body has a through hole at the center. The fixed plate body also has a first adjustment hole and a second adjustment hole for positioning the mounting hole.

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] The tooling fixing plate and calibration device according to the present invention are described below with reference to the accompanying drawings.

[0033] like Figure 1As shown, in this embodiment, this application provides a tooling fixing plate for motor calibration. The motor includes a motor body 101 and a drive shaft 102 mounted on the motor body 101. The motor body 101 has multiple mounting holes 103. The tooling fixing plate includes a fixing plate body 1 and a locking fastener. A through hole 11 is provided at the center of the fixing plate body 1. The fixing plate body 1 also has a first adjustment hole 12 and a second adjustment hole 13 for positioning the mounting holes 103. There are multiple first adjustment holes 12 and second adjustment holes 13, which are arranged circumferentially around the through hole 11. At least one second adjustment hole 13 is provided between any two adjacent first adjustment holes 12. Both the first adjustment holes 12 and the second adjustment holes 13 extend radially along the fixing plate body 1. The locking fastener is used to connect the first adjustment hole 12 or the second adjustment hole 13 to the multiple mounting holes 103 one by one. The distance between the mounting hole 103 and the drive shaft 102 varies on motors of different specifications. The drive locking fastener slides along the first adjustment hole 12 or the second adjustment hole 13 for adjustment, and then locks itself to the mounting hole 103 on the motor. This allows for locking of different motor models. In this embodiment, by providing the first adjustment hole 12 and the second adjustment hole 13 extending radially along the fixed disk body 1, it ensures that motors of various specifications can be installed on the fixed disk body 1, providing good versatility and meeting the calibration requirements of various motor models. The locking fastener is a screw, as used in the prior art.

[0034] like Figure 2 As shown, in this embodiment, the first adjustment hole 12 and the second adjustment hole 13 are both oblong holes and are arranged alternately at equal intervals along the circumference. The regular shape can better accommodate different models of motors and ensure the stability of the fastener connection. Compared with the through hole in the prior art, it provides a larger position adjustment range for motor installation, making it easier for the fastener to be locked to the mounting hole 103 on the motor by passing through the first adjustment hole 12 or the second adjustment hole 13 in sequence.

[0035] like Figure 2As shown, in this embodiment, the locking device includes a plug-in portion and a limiting portion. The fixing plate body 1 also has a first countersunk hole 14 corresponding to and communicating with the first adjustment hole 12 and a second countersunk hole 15 corresponding to and communicating with the second adjustment hole 13. Both the first countersunk hole 14 and the second countersunk hole 15 are used to accommodate the limiting portion. The plug-in portion passes through the first adjustment hole 12 or the second adjustment hole 13. It should be noted that both the first adjustment hole 12 and the second adjustment hole 13 are composed of a straight hole portion and a round hole portion connected to both ends of the straight hole portion along its length. The distance from the center of the round hole portion of the first adjustment hole 12 and the second adjustment hole 13 facing the through hole 11 to the center of the through hole 11 is 105 mm, and the distance from the center of the round hole portion of the first adjustment hole 12 and the second adjustment hole 13 away from the through hole 11 to the center of the through hole 11 is 199 mm. Here, the locking device is a screw in the prior art, and the limiting portion refers to the head of the screw.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the groove depth of the first countersunk hole 14 ranges from 9mm to 11mm, and the groove depth of the second countersunk hole 15 ranges from 12mm to 14mm. Preferably, the groove depth of the first countersunk hole 14 is selected as 9mm, which can better fit the limiting part of the fastener with an M6 thread specification, and the groove depth of the second countersunk hole 15 is selected as 12mm, which can better fit the limiting part of the fastener with an M10 thread specification.

[0037] Furthermore, if an M5 threaded fastener is used to fix the mounting plate body 1 to the motor, a flat washer needs to be added into the groove of the first countersunk hole 14. The M5 threaded fastener passes through the flat washer and presses it firmly against the bottom of the groove of the first countersunk hole 14 to prevent the M5 threaded fastener from shaking, thus ensuring a stable connection and fixation between the mounting plate body 1 and the motor. Similarly, if an M8 threaded fastener is used to fix the mounting plate body 1 to the motor, a flat washer needs to be added into the groove of the second countersunk hole 15. The M8 threaded fastener passes through the flat washer and presses it firmly against the bottom of the groove of the second countersunk hole 15 to prevent the M8 threaded fastener from shaking, thus ensuring a stable connection and fixation between the mounting plate body 1 and the motor. It should be noted that if the mounting hole 103 on the motor is not a through hole, the fixed plate body 1 can be locked to the motor simply by using the fastener; if the mounting hole 103 on the motor is a through hole, an additional nut can be added, and the fixed plate body 1 can be stably locked to the motor by the thread engagement of the fastener and the nut, which further improves the stability of the tooling fixed plate calibration operation.

[0038] like Figure 1 and Figure 4As shown, in this embodiment, the tooling fixing plate also includes a stop connecting ring 2. The fixing plate body 1 also has a stop hole 16 for the stop connecting ring 2 to be locked in place. The through hole 11 communicates with the stop hole 16, and the groove depth of the stop hole 16 ranges from 10mm to 12mm. Preferably, the groove depth of the stop hole 16 is set to 10mm, which better accommodates the stop connecting ring 2, allowing the motor to be stably positioned relative to the tooling fixing plate, thus improving the stability of motor calibration. The stop connecting ring 2 has a protrusion that matches the stop hole 16.

[0039] like Figure 2 As shown, in this embodiment, the fixed plate body 1 is also provided with a plurality of fixing holes 17 symmetrically arranged at the center of the through holes 11. The plurality of fixing holes 17 are all located close to the outer periphery of the fixed plate body 1, so that the fixed plate body 1 can be fixed to the stand with bolts, and the fixed plate body 1 can be prevented from shaking during the calibration of the power supply motor. Among them, the plurality of first adjustment holes 12 and the plurality of second adjustment holes 13 on the fixed plate body 1 are all located between the fixing holes 17 and the through holes 11, and are arranged in a regular manner to accommodate different models of motors.

[0040] like Figure 2 As shown, in this embodiment, the number of the first adjustment holes 12 and the second adjustment holes 13 is the same and is a multiple of 4, so as to better adapt to the mounting holes 103 on the motor. It should be noted that the number of mounting holes 103 on the motor is generally set to a multiple of four. Furthermore, when there are many first adjustment holes 12 and second adjustment holes 13, that is, as in this embodiment, there are 12 first adjustment holes 12 and 12 second adjustment holes 13, the mounting holes 103 on the motor can still adapt to the tooling fixing plate even if they are not arranged at equal intervals around the drive shaft 102.

[0041] like Figure 2 As shown, in this embodiment, the width of the first adjustment hole 12 is smaller than the width of the second adjustment hole 13. Specifically, in this embodiment, the width of the first adjustment hole 12 is set to 6.6 mm, which allows the insertion part of the M6 ​​threaded fastener to be inserted, and the width of the second adjustment hole 13 is set to 11 mm, which allows the insertion part of the M10 threaded fastener to be inserted, so as to stably lock the motor onto the fixed plate body 1.

[0042] In this embodiment, the fixing plate body 1 is made of metal. Specifically, the fixing plate body 1 can be made of materials such as aluminum alloy, which has high structural strength.

[0043] Specifically, the steps for calibrating the motor using the tooling fixing plate described in this application are as follows:

[0044] First, bolts secure the motor to the frame through multiple fixing holes 17 on the fixed plate body 1, ensuring that the fixed plate body 1 does not move arbitrarily, and ensuring that the stop hole 16 is located on the side of the tooling fixed plate away from the frame. Then, the protrusion of the stop connecting ring 2 is inserted into the stop hole 16 for limiting and locking, and the motor is then fitted onto the stop connecting ring 2 for easy positioning, ensuring that the motor mounted on the stop connecting ring 2 is concentric with the tooling fixed plate. Next, multiple locking fasteners sequentially lock the motor to the fixed plate body 1 through the first adjustment hole 12 and the mounting hole 103, and multiple locking fasteners sequentially lock the motor to the fixed plate body 1 through the second adjustment hole 13 and the mounting hole 103, thus completing the motor calibration operation. The number of locking fasteners can be adjusted according to the number of mounting holes 103 on the motor.

[0045] Using the tooling fixing plate in this embodiment eliminates the need to design and manufacture bulky tooling fixing plates for each type of motor. Only one or a few sets of this tooling fixing plate are needed, which, when used with the concentric connecting ring 2, can be fixed to meet the calibration needs of various motors. This reduces the costs associated with frequent redesign and manufacturing of fixing plates, effectively saving production costs. Furthermore, using the tooling fixing plate in this embodiment, when calibrating different motor models, operators do not need to wait for the design and manufacture of new fixing plates. They can simply use the existing tooling fixing plate, through simple hole selection and bolt installation—that is, adjusting the position of the locking fastener along the first adjustment hole 12 or the second adjustment hole 13—and lock the motor and tooling fixing plate together to quickly fix the motor and begin the calibration process. This effectively shortens the preparation time for motor calibration and improves the efficiency of motor calibration. In this embodiment, the design of the oblong hole allows for a certain amount of position adjustment space during motor installation. When it is necessary to make a fine adjustment to the installation angle or position of the motor, there is no need to redesign the tooling fixing plate or perform additional processing on the motor. Simply loosen the bolts, adjust the position of the motor within the range of the oblong hole, and then tighten them again, which improves the flexibility of motor installation.

[0046] In this embodiment, a calibration device is proposed, including a stand and a tooling holder mounted on the stand as described above. Since the calibration device adopts all embodiments of the tooling holder, it also has all the beneficial effects brought by the tooling holder, which will not be described in detail here.
