Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices, and in particular relates to a motor housing positioning clamping device. Background Art

[0002] During the processing of the machine casing, when installing the junction box on the motor casing, it is necessary to determine the installation position of the junction box on the motor casing and mark it accurately, drill holes or grooves on the motor casing to install fasteners, and connect it to the junction box through fasteners. During installation, the motor casing needs to be positioned and clamped. Generally, a vise is used for clamping, which only fixes the motor casing. The actual clamping effect is not good, and the force point is unstable, which makes it easy for the motor casing to shake during processing.

[0003] Chinese patent application number 2022231520695 discloses a motor housing processing fixture, including a base plate, a first support plate and a second support plate are installed on the base plate, the angle between the first support plate and the second support plate is 90 degrees, and a slide rail is also provided on the base plate, a slider is slidably fitted on the slide rail, a clamping seat is provided on the top of the slider, and the clamping seat is provided with a right-angle opening groove, a motor housing component is clamped between the clamping seat, the first support plate and the second support plate, and the motor housing component is assembled on a positioning seat, a quick clamping mechanism is provided on one side of the clamping seat, and the quick clamping mechanism is installed on the base.

[0004] The above patent solution has the effect of improving the fastening performance, but because it needs to be clamped with multiple fixings during fixation, this increases the installation time. If a large number of motor housings need to be positioned, the overall installation time will be greatly increased. Utility Model Content

[0023] like Figure 1-3As shown, a motor housing positioning clamping device comprises a clamping seat 1, the clamping seat 1 is fixed on the corresponding ground or equipment, a main accommodating space 2 is provided inside the clamping seat 1, a first convex portion 3 and a second convex portion 4 are respectively provided on both sides of the clamping seat 1, a side accommodating space 5 is opened on the first convex portion 3 and the second convex portion 4, a first locking structure is provided on the first convex portion 3, and a second locking structure is provided on the second convex portion 4. The motor housing is composed of a main body and connecting parts on both sides of the front end of the main body. The motor is placed in the main accommodating space 2 on the clamping seat 1, and then the connecting parts on both sides of the motor are respectively placed in the side accommodating spaces 5 in the first convex portion 3 and the second convex portion 4. The positioning clamping can be completed by locking the connecting parts on both sides of the motor through two locking structures. Through the main accommodating space 2 of the clamping seat 1 and the side accommodating spaces 5 of the first convex portion 3 and the second convex portion 4, the main body of the motor housing can be fully supported and fixed. This design makes it difficult for the motor housing to shake or displace during processing, thereby improving the stability and accuracy of processing. The bottom of the clamping seat 1 is an arc-shaped structure, and an elastic notch 18 is provided in the middle of the arc-shaped structure. The design of the elastic notch 18 may enable the clamping seat 1 to have a certain self-adjustment ability during installation, thereby simplifying the installation process. Even if the size or shape of the motor is slightly deviated, the clamping seat 1 can adapt to it through the deformation of the elastic notch 18, thereby simplifying the positioning and fixing steps of the motor housing.

[0024] In this embodiment, the first locking structure includes a hook plate 6, one end of which is connected to the side of the first protrusion 3, and the other end of the hook plate 6 is extended to form a hook portion 7, and a positioning clamping space 8 is formed between the hook portion 7 and the front end surface of the first protrusion 3, and the second locking structure includes a bolt locking hole 9, which is arranged in the second protrusion 4. During installation, the connecting plate on one side of the motor housing is first clamped into the space 8, and then the connecting part on one side of the motor housing is clamped into the side accommodation space 5 of the first protrusion 3, and the entire motor housing is clamped into the main accommodation space 2, and finally the connecting part on the other side of the motor housing is clamped into the side accommodation space 5 of the second protrusion 4, and then the connecting part on the other side of the motor housing is bolted to the second protrusion 4 to complete the fixation. Through the hook plate 6 of the first protrusion 3 and the bolt locking hole 9 of the second protrusion 4, the device can quickly and effectively fix the motor housing. The design of the hook plate 6 allows the connection part on one side of the motor housing to be quickly inserted into the positioning and clamping space 8, while the bolt locking hole 9 ensures the stable locking of the connection part on the other side. This design greatly simplifies the positioning and clamping steps and improves work efficiency. Example 2

[0025] Combination Figure 4-5The present embodiment is an improvement on the first locking structure and the second locking structure. In the present embodiment, the first locking structure includes a first mounting hole 10 arranged in the first convex portion 3, a first clamping rod 11 is fixed in the first mounting hole 10, first clamping portions 12 are arranged on both sides of the top of the first clamping rod 11, the cross-section of the first clamping portion 12 is a right triangle, a first deformation space 13 is arranged above the first clamping rod 11 and located in the middle of the two first clamping portions 12, the second locking structure includes a second mounting hole 14 arranged in the second convex portion 4, a second clamping rod 15 is fixed in the second mounting hole 14, second clamping portions 16 are arranged on both sides of the top of the second clamping rod 15, the cross-section of the second clamping portion 16 is a right triangle, a second deformation space 17 is arranged above the second clamping rod 15 and located in the middle of the two second clamping portions 16.

[0026] During installation, it is only necessary to match the main body of the motor housing with the main accommodating space 2, match the connecting parts on both sides of the motor housing with the first convex part 3 and the second convex part 4 respectively, and then insert the entire motor housing into the main accommodating space 2 smoothly. The connecting parts on both sides of the motor housing are provided with connecting holes. During insertion, the two first clamping parts 12 on the first clamping rod 11 form a structure close to a cone as a whole. A gap is provided between the two first clamping parts 12 to communicate with the first deformation space 13. The maximum distance between the two first clamping parts 12 is greater than the connecting hole on the connecting part. However, during the process of clamping into the connecting hole on the connecting part, the two first clamping parts 12 will shrink toward the middle until the maximum distance between the two first clamping parts 12 is the same as the connecting hole. When the two first clamping parts 12 completely pass through the connecting hole, the two first clamping parts 12 are no longer restricted by the connecting hole and return to their original state, thereby being tightly clamped on the connecting part. The second clamping part 16 on the second clamping rod 15 is also the same when inserted. Through the first mounting hole 10 in the first protrusion 3 and the second mounting hole 14 in the second protrusion 4, and the first clamping rod 11 and the second clamping rod 15 fixed therein, the motor housing can be quickly and accurately positioned and fixed on the clamping seat 1. The operator only needs to insert the motor housing flatly into the main accommodating space 2 without complicated operating skills or tools, which further simplifies the operating process. This design further simplifies the installation steps and improves work efficiency.

[0027] Support legs 19 are provided on both sides of the bottom of the clamping seat 1. The bottom of the support legs 19 is a bent structure 20. The support legs 19 provide support points. The support legs 19 are screwed to the corresponding ground or equipment through the bent structure 20, making the entire device more stable. When the motor is working, this stability can effectively reduce the shaking and displacement caused by vibration or impact, thereby ensuring the smoothness and reliability of the motor operation.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
