[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0031] See also Figure 1-Figure 6 As shown, this embodiment discloses a yoke off-line detection press-fitting machine, including a base 10 and a press-fitting head 80. The press-fitting head 80 is located above the base 10 and is driven to rise and fall by a first driving source 81. The press-fitting head 80 adopts the existing technology to press and assemble the yoke and the motor component to be assembled. Different from the existing technology, Figure 2As shown, a mounting groove 45 is opened on the base 10, one end of the mounting groove 45 is a press-fitting station 11a, and the other end is a detection station 11b. The press-fitting head 80 is located directly above the press-fitting station 11a. The press-fitting station 11a is used to press-fit the yoke, and the detection station 11b is used to realize the power-on detection of the assembled motor assembly.

[0032] like Figure 3 , Figure 4 , Figure 5 As shown, a connecting member 20 capable of horizontal sliding and a second driving source 30 for driving the connecting member 20 to slide horizontally are arranged in the installation groove 45. The connecting member 20 is driven by the second driving source 30 and can slide back and forth between the pressing station 11a and the inspection station 11b; a lifting platform 40 and a third driving source 50 are arranged in the inspection station 11b, a connecting buckle 60 is arranged on the side wall of the lifting platform 40, and the third driving source 50 drives the lifting platform 40 to rise and fall; when the lifting platform 40 descends, the connecting buckle 60 is engaged with the connecting member 20, and the second driving source 30 can drive the lifting platform 40 to slide horizontally; when the lifting platform 40 rises, the connecting buckle 60 is separated from the connecting member 20, and the lifting platform 40 is separated from the installation groove 45.

[0033] In order to ensure that the connection 20 can move horizontally, such as Figure 5 As shown, a horizontal guide rod 14 is disposed in the mounting groove 45 , and the connecting member 20 is sleeved on the horizontal guide rod 14 .

[0034] The connecting member 20 in this embodiment is an integrally formed structure. Figure 6 As shown, the connector 20 is provided with a slot 21. Figure 5 As shown, the connecting buckle 60 is U-shaped, and the opening of the connecting buckle 60 faces downward. When the lifting platform 40 descends, the connecting buckle 60 is engaged in the slot 21 of the connecting member 20. At this time, the second driving source 30 can drive the lifting platform 40 to translate toward the pressing station 11a through the cooperation of the connecting member 20 and the connecting buckle 60.

[0035] like Figure 5 As shown, the lifting platform 40 includes a top plate 41, an insulating plate 42, and a bottom plate 43. The provision of the insulating plate 42 ensures that no current is transmitted to the base 10 during detection, thereby ensuring the safety of the detection. The top plate 41, the insulating plate 42, and the bottom plate 43 are connected and fixed in sequence from top to bottom, and the third driving source 50 is connected and fixed to the bottom of the bottom plate 43. In this embodiment, a plurality of third driving sources 50 are provided, and are located at the four corners of the lifting platform 40, which can ensure the stability of the overall lifting of the lifting platform 40.

[0036] Since the lifting platform 40 is always moving horizontally on the base 10, in order to reduce the wear of the base 10, Figure 4As shown, the upper end surfaces of both sides of the mounting groove 45 of this embodiment are fixed with first wear-resistant plates 12, and when the connecting buckle 60 is buckled with the connecting member 20, both sides of the top plate 41 can slide along the first wear-resistant plates 12. Similarly, in order to ensure the bottom of the lifting platform 40, the bottom of both sides of the corresponding bottom plate 43 are provided with second wear-resistant plates 44.

[0037] During the specific installation process, the first wear-resistant plate 12 and the second wear-resistant plate 44 can be fixed with bolts, which makes disassembly and installation more convenient, and the sunken bolt holes are used for locking. This ensures that the lifting platform 40 will not be affected by the bolts during translation, thereby ensuring smooth translation.

[0038] A circular boss mounting seat (not shown in the figure) is provided in the middle of the upper end surface of the top plate 41. The circular boss mounting seat can be fixedly mounted on the top plate 41, and the circular boss mounting seat matches the bottom shape of the assembled product; a plurality of inverted T-shaped grooves 45 are provided on the upper end surface of the top plate 41, and a positioning bolt is movably provided in any inverted T-shaped groove 45. During installation, the component product to be assembled is placed on the circular boss, which plays the role of determining the center of the circle to ensure that when it moves to the bottom of the press-fitting head 80, it corresponds to the center of the circle of the press-fitting head 80, thereby ensuring the accuracy of the press-fitting.

[0039] like Figure 4 , Figure 5 As shown, the third driving source 50 is fixedly mounted on the support plate 13, and the support plate is fixed in the mounting groove 45 of the detection station 11b. There are multiple third driving sources 50, and a matching guide assembly 70 is arranged between the support plate 13 and the bottom plate 43. Figure 5 As shown, the guide assembly 70 includes a guide sleeve 71 fixed on the support plate 13 and a guide column 72 fixed on the lower end surface of the base plate 43. A plurality of guide sleeves 71 and guide columns 72 are matched and arranged, and each guide column 72 passes through the corresponding guide sleeve 71.

[0040] In this embodiment, the first driving source 81 , the second driving source 30 , and the third driving source 50 are air cylinders, hydraulic cylinders, or servo linear modules.

[0041] The working principle of this embodiment is that the yoke and the motor assembly to be assembled are placed on the circular boss mounting seat of the lifting platform 40 manually or by a manipulator, and the bolts on the inverted T-slot 45 are locked to position the product. The second driving source 30 is then used to drive the link 20 to move to the detection station 11b, and the third driving source 50 drives the lifting platform 40 to sink until the connecting buckle 60 is engaged in the slot 21 of the connecting member 20. The second driving source 30 is then used to drive the lifting platform 40 to move to the press-fitting station 11a, and the first driving source 81 drives the press-fitting head 80 to sink, and the yoke is press-fitted into the motor assembly product. After press-fitting, the second driving source 30 drives the lifting platform 40 to reset to the detection station 11b, and the third driving source 50 drives the lifting platform 40 to rise, and the connecting buckle 60 is separated from the slot 21 of the connecting member 20. At the same time, the lifting platform 40 is higher than the mounting slot 45, and the current during detection will not pass through the guide base 10. After the detection is completed, the material can be unloaded manually or by a manipulator.

[0042] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
